This webpage collects some of the computing stuffs I've written for either my research or study. Please let me know if you have any comments. Note that some of programs are not available right now because I am re-organizing them.

 

    Stata: Generalized Entropy Mobility Measure

     This program accompanies my on-going project with Essie Maasoumi on dynamic mobility

     in China. The measure is based on Maasoumi and Trede (2001) and Maasoumi and

     Zandvakili (1986, 1990).

     useful.
