Naturally I agree with Maarten on the point of list practice. He is
referring to an explicit request that posters use their full names.
2.1.3 within http://www.stata.com/support/faqs/resources/statalist-faq/#tojoin
means exactly what it says.
On the substantive question,
(1) if "series" means what I think it does, a time series of some
kind, then note that Kolmogorov-Smirnov tests tacitly assume mutual
(2) the most direct way of comparing a distribution with t with 8 d.f.
is a quantile-quantile plot.
Example code to show how easy this is:
sysuse auto, clear
egen rank = rank(mpg), unique
su mpg, meanonly
local N = r(N)
gen tquantile = -invttail(8, (rank - 0.5) / `N')
scatter mpg tquantile
