I am new to Stata and propensity score matching. I have 143, 110 control and
5,862 treated in my matched samples. I ran pscore2 to get this. 

Once I ran pscore I ran a radius matching method with the following command:

. attr englleve sch_grp sex_1 rd07leve, comsup boot reps(100) dots logit

The process has given me:

ATT estimation with the Radius Matching method

Analytical standard errors



n. treat.   n. contr.         ATT   Std. Err.           t



     5862      143110      -0.073       0.008      -8.673



Note: the numbers of treated and controls refer to actual

matches within radius


The process has now run for 36 hours (MP2 version of Stata 12.1 AMD 2 core,
WinXP pro 32byte). Should I let it run longer or am I hopelessly lost in
some computational problem? Or did I miss specify the model?

Thanks for your help and advice
