What is the IFs Network Diagram?

The IFs Network Di agram is an interactive visualization of the internal structure of the International Futures (IFs) model. in IFs and how they influence one another. It is a map of the IFs model’s logic. You can use it to answer questions like “What affects this variable?” or “What does this variable affect?”. Users can explore how major system sectors interact; at the variable level, they can interrogate specific influence pathways by examining drivers (inputs), outcomes (outputs), degrees of separation, and shortest paths between variables. In this way, the IFs Network Diagram functions as a transparency and learning tool, allowing users to inspect and reason about what influences what is within the IFs system, rather than treating the model as a black box.

Views

The diagram has three levels:

* Macro view: Shows the 11 major categories in IFs

* Use this view to see the big picture of how sectors connect

* Meso view: Shows the subcategories within each meso category and their connections

* Use this view to gain more detail without seeing every variable

* Variable view: Shows all individual variables and parameters (nodes) and their links

* Use this to explore specific variables

Macro & Meso Interactions:

* Hover over a node to see an information box (Tool Box)

* Click and drag a node to better visualize connections or move it around the screen

Basic Controls

These options control what you see in the diagram:

* Search for variables (Top Right Corner):

* Type a variable or parameter name

* Click it in the search box to highlight it in the diagram

* Zoom In / Zoom Out / Fit to Screen (Bottom Left Corner):

* Download:

* Download a .png image of the current view

* Help Panel:

* Opens pop-up with link to full instructions

Variable View

Some features are only available in Variable View:

* Toggle Layouts – switch between:

* Default: shows all selected nodes and their connections

* Shortest Path: shows the shortest path between two nodes, if they’re connected in the model

* If a node was selected in Default view, it becomes the origin node

* Use the search box to choose the end node

* Nearest Neighbor: shows all nodes that are connected to the selected root node, up to three degrees away

* Degree 1 = directly connected

* Degree 2 = connected through one intermediate node

* Degree 3 = connected through two intermediate nodes

* Use the slider to change the number of degrees shown

Interactive Menu

Use the interactive menu to control which parts of the network are visible:

* Show/Hide Interactive Menu: opens or closes the list of all nodes

* Interactive Menu:

* You can check/uncheck:

* Individual nodes

* Submodules

* Major categories

* Checked = visible

* Unchecked = grayed out in the display

* Unselect all: “Hides” (grays out) all nodes at once

* Allows you to select specific nodes of interest

* Reset: Returns to default layout for your current view

Working with Nodes

When you click on a node in the variable view, it becomes the root node. From there, you can explore what drives it and what it influences.

Node information:

* Tool box (hover)

* Appears when you hover over a node

* Shows: node name, display name, explanation, submodule, and segment

* Tool tip (click)

* Appears when you click a node (in Default view)

* Shows:

* All inputs and outputs to/from that node

* Each connection’s segment, name, and display name

* A shortest path button to jump into Shortest Path mode

Directions and degrees:

* When you select a node:

* It becomes the root node

* Drivers = inputs to the root node

* Outcomes = outputs from the root node

* Degrees = how many steps away another node is

* In the tool tip, you can filter connections:

* Both – show both inputs and outputs

* Only <- show only inputs to the selected node

* Only -> show only outputs from the selected node

Typical Workflows

# Find what affects a variable (its drivers)

# Go to variable view

# Search for the variable and click it

# In the Tool Tip, choose Only <- to see its inputs

# Find what a variable influences (its outcomes)

# Go to variable view

# Search for the variable and click it

# In the Tool Tip, choose Only -> to see its outputs

# Trace a chain of influence between two variables

# In Default, click the starting variable

# Click Shortest Path in the Tool Tip

# Use the search box to choose the end variable

# The tool will show the shortest connection pathway between them

# See all neighbors of a key variable

# Switch to Nearest Neighbor layout

# Choose your root node (or click one in Default first)

# Use the degree slider to expand from immediate neighbors to broader connections

Show Parameters

The Show Parameters button controls whether model parameters are displayed alongside variables in the Variable View.

Parameters represent adjustable model inputs that influence how variables behave in the IFs model. While variables represent outcomes calculated by the model, parameters define assumptions, coefficients, or policy settings that affect those outcomes.

When Show Parameters is turned off (default):

* Only variables are displayed in the diagram.

* The network shows relationships between model outcomes.

When Show Parameters is turned on:

* Parameter nodes appear alongside variables.

* Additional links become visible showing how parameters influence variables in the model.

This option is useful when users want to:

* Explore policy levers or assumptions that affect a variable.

* Understand how model parameters feed into the calculation of outcomes.

* Trace the influence of parameters through the network.

When parameters are displayed:

* Parameter nodes appear visually distinct from variable nodes.

* Their positions are determined by the same linkage structure as variables, ensuring that their placement reflects their relationships within the model.

Use the ''Parameter Search'' feature to search, explore, and choose parameters to adjust for scenario analysis. Use this feature with the ''[[Guide to Scenario Analysis in International Futures (IFs)|Guide to Scenario Analysis in IFs]]'' to find the parameters most useful for the intended intervention or scenario goal. Type the desired parameter name in the search bar, then click '''Search'''. Click on the parameter, which will bring up a few options described below. Click '''Load''' to select this parameter in the scenario tree, to adjust it for a scenario. Click '''Help''' to open the corresponding page in the [[Main Page|Pardee Wiki]], or '''Continue''' to go back to the previous menu or to the Main Menu of IFs.
[[File:Example of Parameter Search Option.png|center|thumb|950x950px|An example of the Parameter Search option for the total fertility rate multiplier tfrm.]]
The options, once a parameter is clicked, include: <span style="color:red">These options are not available for all parameters.
* '''Define''': See a brief definition of what the parameter is.
* '''Block Diagram (Pop-Up)''': Bring up a help-file that shows a diagram that broadly explains how drivers interact for the area of inquiry (agriculture, economics, etc.). There is normally also a textual explanation.
* '''Equations (Pop-Up)''': See the mathematical equations that are used to determine this parameter.

= <span style="font-size:xx-large;">Using the Scenario Tree</span> =
The easiest way to create scenario interventions is to use the ''[[Guide to Scenario Analysis in International Futures (IFs)|Guide to Scenario Analysis in IFs]]'' along with the Parameter Search option, but if desired, use the Scenario Tree. Click on any of the categories in the Scenario Tree (ex., Technological change. to open sub -categories and eventually to open up a parameter choices box. Once this box appears to the right of the scenario tree with parameter names and descriptions, click on any parameter to reveal a few options shown below.
[[File:Example of Scenario Tree usage.png|center|thumb|950x950px|An example of the scenario tree being used for Technological Change, Energy, and with the QEM parameter selected; shows the options that selecting a parameter will reveal.]]
The options include: <span style="color:red">These options are not available for all parameters.

* '''Select''': Choose the parameter in order to change it.
* '''Drivers''': Click to see what variables are affecting the chosen parameter.
* '''Explain (Pop-Up)''': See a causal diagram and an explanation of what affects this parameter.
* '''View Equations (Pop-Up)''': See the mathematical equations that are used to determine this number.
* '''Define''': See a brief definition of what the parameter is.
Once a parameter is chosen by clicking '''Select''' a drop-down will appear to choose either a particular country or group. Choose the desired country or group by clicking on it. Another drop-down will appear if the parameter has dimensions (ex., Male, Female, Total), click on the desired dimension choice, and repeat if the parameter has multiple dimension choices. After this, the selected parameter will appear to the right of the tree with its base value or scenario value (if opened within an already made scenario) shown. An example of this screen is shown below.
[[File:Example of Parameter Adjustment on Scenario Tree.png|center|thumb|950x950px|An example of a parameter selected to adjust on the Quick Scenario Analysis Tree page. Example of the Government expenditures by destination multiplier (Health) parameter for Argentina.]]
Adjust the initial parameter value to make interventions using default changes by clicking the bubble for '''High''' or '''Low''', or to return to the base, click '''Base'''. Instead of using the default options, use the slider or enter the desired number into the field above the slider and click '''Apply'''. Using this slider or field option will apply that value to the whole time horizon to the year 2150, with an initial shift period based upon the choice from the '''Shift Years''' dropdown. In the example, the value is 5.177, and the shift years are 10, so the parameter interpolates from 1 to 5.177 from 2020 to 2030 and then stays at that value for the whole horizon. To have even more control of the parameter, click '''Fully Customize'''.
[[File:Example of the Fully Customize Parameter option.png|center|thumb|950x950px|An example of the Fully Customize option for parameter changes. Example of the Government expenditures by destination multiplier (Health) parameter for Argentina.]]
The '''Fully Customize''' option allows more control over parameter behavior. The '''Information''' table displays information on parameter value for a given year, and the minimum and maximum values that IFs allows users to intervene on. If above or below these, a warning message will appear. Use the '''Year''' field in this table to jump to a particular year to view the value or to start an intervention from.

The '''Change Numerically''' table is where the changes to a parameter are made. Use the '''Next Year''' or '''Previous Year''' buttons to change the '''Year''' field by one. Once at the desired year to start an intervention shown in the '''Year''' field, enter in the '''Desired Value''' field the value to change the parameter to, use the '''Years to Repeat or Interpolate''' field to set the number of years for the intervention to take place (this includes the current year so to increase the value for the next 10 years, enter 11). Click '''Change/Repeat''' to apply the desired value for the number of years entered (for example, an increase to 8 for 61 years from 2090 to 2150, shown above) or click '''Interpolate''' to smoothly shift the value over the number of years entered from the current value to the desired value. Continue to use the '''Change Numerically''' table until the parameter is adjusted as desired.

To ensure that the parameter is adjusted as desired, hover over the graph on the right side of the page to see the parameter value in any given year. Click '''Register Change''' to apply this intervention to the current scenario, '''Cancel All Changes''' to clear the current parameter adjustments, '''Exit to Scenario Tree''' to return to the scenario tree, or '''Help''' to open the corresponding page in the [[Main Page|Pardee Wiki]].

Change Selected Functions

2025-09-24T17:45:56Z

Abdelrahman.Ibrahim: /* Bivariate Functions */

Variables are forecast based on mathematical relationships that are represented by functions within IFs. These functions can be changed based on different understandings of relationships between variables. Change the relationships between two variables or multiple variables using the ''Bivariate'' and ''Multivariate function'' pages.

= <span style="font-size:xx-large;">Bivariate Functions</span> =

To open the ''Bivariate Function'' page from the Main Menu of IFs: choose '''Scenario''', '''Change Selected Functions''', and click '''''Bivariate Function.''''' Once on the ''Bivariate Function'' page, search for a particular function in the '''Filter Functions (press enter)''' field or scroll through the '''Function (click to see/edit)''' dropdown to view a relationship that is already in IFs. Use the filter options ('''Used in Run''', '''Used in Historical Run,''' etc.) to the right of the dropdown to filter for functions that are used for particular model tasks, or not used at all.
[[File:Example of Bivariate Function page.png|center|thumb|950x950px|An example of the Bivariate Function page used to change functions in IFs.]]
When a function is clicked, the relationship of the function will be shown in graph form at the bottom of the screen. Depending on the type of function, an R-squared and standard error of the relationship may also be shown below the graph. Export the graph by clicking on the three lines in the upper right corner of the graph, then select the desired format to export.

To change a chosen function, use the '''Table Functions Points''' frame option or the '''Analytic Function''' button option to specify a new relationship.

'''Table Functions Points''': A table function relationship is based upon lines that connect given points. In the Table '''Function Points''' frame, there are boxes for specifying the X-axis and Y-axis values. Specify a desired point by entering the X and Y axis values, then click '''Add'''. Add as many points as desired, and click '''Previous''' and '''Next''' to move between already created points. Click '''Delete''' to remove a point from the graph. When the points desired to create a function with are all added, click '''Alter''' to alter the function to now be based on this new relationship.

'''Analytic Function''': Click to open the ''Specify Analytic Function'' page. Use this page to change the mathematical formula of a function by adjusting its function terms. A function based on a linear regression will only have a and b1 terms, and altering other bs will change the whole function type. More complex functions will use different b terms, for example, an exponential will use b2 and a logarithmic b4.
[[File:Example of the Specify Analytic Function page.png|center|thumb|950x950px|An example of the Specify Analytic Function page, for GDP and car sales.]]
Change the '''Display Figure from X Value''' and '''To X Value''' fields to change the graph in the ''Bivariate Functions'' screen. Once the function is changed as desired, click '''Save and Continue''' to save and return to the ''Bivariate Functions'' page or '''Exit - Abandon Changes''' to return without saving the change.

Click '''Reverse Changes''' to return to the default for the selected function, '''Help''' to open the corresponding page in the [[Main Page|Pardee Wiki]], or '''Exit''' to return to the ''Main Menu''. After clicking '''Exit,''' IFs gives a very important informational warning on how any function changes will be active only in the current session of IFs. Starting IFs again resets all functions to standard values. Moreover, although runs of the model that you make with altered functions will reflect the changes in functions, no information about the changed functions is saved with the model.RUN files. Keep track of these changes somewhere for replicability.

Now run the model and create a new working file that reflects the changed functions and their impact on all computations in IFs. Compare this run file (or a saved version of it) with the base case or with other scenarios.

= <span style="font-size:xx-large;">Multivariate Functions</span> =

Begin at the Main Menu of IFs. Choose '''Scenario''', '''Change Selected Functions''', and click '''''Bivariate Function.''''' This page displays a table with multivariate function names, their intercept, R-squared, and standard errors. Search for a particular function using the search bar or scroll through the table to find the desired function. Use the filter options ('''Used in Run''', '''Used in Historical Run,''' etc.) to the right of the table to filter for functions that are used for particular model tasks, or not used at all.
[[File:Example of Multivariate Functions page.png|center|thumb|950x950px|An example of the Multivariate Functions page.]]
Click on any intercept to change the intercept term or on any function name to alter the other terms used in the function. A new page will open, where changes to function terms can be made.
[[File:Example of Change Multivariate Function Sreen.png|center|thumb|950x950px|An example of the Change Multivariate Function screen for Bilateral Aid Exports.]]
Click on the desired b coefficient to change the value for that coefficient. The b coefficients are based upon the standard function shown above the table; for example, b4 is for logarithmic functions. Once clicked, enter the desired value, then click '''Continue''' to save that term and repeat for each coefficient term desired to change. Then click '''Continue''' to save and update the function.

Changing functions gives you a powerful tool for using IFs to investigate possible futures. To an extent, it allows you to change the model itself.
