Computer code and other resources

This page gives access to resources for mathematical modellers, statisticians and econometricians. It is work in progress and I will add to it bit by bit. Stata commands can be found in the EMU project Stata resources.

Modelling EQ-5D

Computer code

The following files can be downloaded from the Computer code downloads box on the right. 

Adjusted Limited Dependent Variable Mixture Model for cross section datasets

  • Log-likelihood function and equation to calculate predicted EQ-5D [Download: ALDVMM cross section - description (pdf)]
  • GAUSS code to estimate the model [Download: ALDVMM cross section - GAUSS code (txt)]
  • STATA module ALDVMM available soon (currently under testing)
