I�m comparing the mean of a sample by group, this is, comparing the
mean of the income earned for males and females. I�m using the Stata -
ttest - command, but i�m a bit confused because this command doesn�t
allows using weights (fweights) and I think that this affects the
results, doesn�t it?
Do you know another way to compare the means of the sample using weights?
=======================================================
You don't tell us what kind of data you have. If you have summary
data with N, mean, and SD for each groups, you can use -ttesti-.
If you have a dataset where an observation may represent several
individuals (the number defined by -n-), you could
expand n
before -ttest-.
Hope this helps
