Hi,
 
I need to conduct a difference of means ttest using data where each observation (which is a probability, incidentally) has a standard error.  Usually, from what I can gather, the ttest command assumes that the standard error for each observation is 0.  Is there any way that I can tell STATA, instead, that each observation has a different standard error, which I specify in a second variable?
 
Thanks very much.  I appreciate your help!
Rikhil
