The grid gives you the opportunity to go into all issue areas and all countries and change any values you wish of the raw data. To narrow down your selection, simply click on Please remember that, if you do so, you will need to rebuild the base case again (after indicating the issue area(s) in which you have changed data) and then rerun the model. Also please remember that any changes you make to the raw data are "permanent" and do not disappear after you exit IFs: the only ways to reverse them are to do so number-by-number or to reinstall IFs.

=== Importing Data from Excel Files ===
'''Import Data''' (Single Series)


This feature of IFs can be found by selecting Extended Features from the Main Menu, Manage Country Data, Historic Data File Processing and then Import XLS Data.
Allows the user to import a single new data series (e.g., a custom GDP estimate) from an excel file into IFs for a specific country or variable. The user can a upload a file by selecting Choose File at the top right center. This interface present user with couple of options like Aggreg. rule, Decimal Places and Existing Variables for the refine their data. Of particular importance among these is the Data Dictionary. This gives the user access to other values and options housed in the View Master Dictionary (including; Variable, Series, CoVaTrA, Cohort and Definition           etc).


When you choose to import large amounts of data into IFs via Excel, choose Import Data From XLS File. This will add an .xls access file to the historic data set for IFs.


Choosing this option will cause a window to appear that will look similarly to the one below:

'''Vet and Merge Imported Data'''


Initially, it would be advised to change the Series Orientation function located on the right hand side of this menu. Identify how your data set is orientated and match that to one of the options. You will notice that the graph below changes to visually represent the specific data orientation that you choose.
This feature checks the quality and integration  for newly imported data. It reviews the data for errors and merges it into the model's master historical database. Marking Threshold enable the user to manipulate data in Years, Points and Differences by Percent or Unit.


After you have chosen the Series Orientation, click on the File option located at the top of the menu. You will then be prompted to select an Excel file. After you have made your selection, the file will be loaded into the Import Excel Data form. You will then be prompted to select certain Excel Sheets. These can be seen at the bottom of the Excel file after it is opened. They may have different names or simply be distinguished as "Sheet 1", "Sheet 2", etc. To see the Excel file you have selected, click on Viet Excel.


After you have selected your Excel file, you must further specify the orientation of the data so that IFs knows how to read the data after it has been imported. Fill in the Country Names Start at, Years Start at and Series Name Start at forms before proceeding. To finish the process, you must fill in some more specific information that will help IFs categorize your data. If you have questions, you can consult the Data Dictionary located in the lower-middle of the menu. When finished, click Import.

Other options include Scaling, which allows users to change their data set values by a multiplier. Finally, users are asked to specify a name for their Variable list as well as a brief description.

This feature of IFs can be found by selecting Extended Features from the Main Menu, Manage Country Data, Historic Data File Processing and then Remove Data From Years.
A specialized function for importing new population datasets, which are critical for the model's demographic core. This allow users to load their data.  


This feature allows users to remove data for all years except for 5 year intervals.

This feature of IFs can be found by selecting Extended Features from the Main Menu, Manage Country Data, Historic Data File Processing and then Identify and Save Years.
'''Earliest Data, Add or Update, Most Recent Data, Add or Update, Most Recent Adjusted Data, Add or Update'''


This feature allows users to identify and save data years if they have made any substantive change to the years in the raw data file. 
These three options provide granular control for updating specific years within an existing data series in IFs. They let users patch the historical record at its start, its latest point, or with a statistically adjusted recent estimate.

To access Manage Groups/Countries/Regions, click on Extended Features on the Main Menu of IFs. There you will find three sub-sub-options: Identify Group or Country/Region Members, Change Grouping/Regionalization, and Display Regionally Aggregated Data.

This feature of IFs allows users to delve more deeply into the structure and membership of groups or Glists that are used in IFs. Users also can create their own groups or alter membership within an existing group to suit their purpose.

Identify Group or Country/Region Members allows IFs users to identify which countries/regions are represented in certain groups. Upon selecting a group (OECD or Afr-SubSahar) from the list on the left, its constituent members will be shown in the right-hand panel. Similarily, when the Using Regions option is selected, the list on the left will change from groups to a list of countries.
