$HDI_{\gamma }={\frac {LifeExpInd_{\gamma }+LitInd+GDPInd}{3}}$

where

$LifeExpInd={\frac {LIFEXP_{\gamma }-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}}$

Failed to parse (unknown function "\gammma"): {\displaystyle LitInd=LIT_{\gammma}/100}

<math>GDPInd=\frac{Log(GDPPCP_{\gamma}*1000)-Log(100)}{Log(40000)-Log(100)}
