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!
