st: hotellings t-sq. test question
Hi, haven't done much with stata before, but I have a paired sample data
set. Problem is that the sample resembles a chi-sq distribution rather
than a normal distribution (can't assume normality). Hence I was
thinking that using a Hotelling's T-sq. test would be more appropriate
that a paired-sample t-test. I need the test to compare means between
the pairs, but am uncertain of how to use the by(groupvar) option.
right now I have:
egen grp_a = group(emp_2005);
hotelling emp_2003 emp_2005, by(grp_a);
but I'm fairly sure that the group division is not what I am looking for.
Any help would be much appreciated.
