How about
g double t = m + sd* invnorm(uniform())/sqrt( invchi2(_N-3), uniform() )

Dear statalisters,
I would like to generate a new variable called "x", in which "x" has a
t-distribution with n-3 degrees of freedom (where n is the number of new
generated observations), a mean "m" and a standard deviation, "sd", that
is:
x ~ t-distribution[n-3 df] (m, sd)
How do I obtain a set of 100 new observations assuming that m=0.4 and
sd=0.05 using Stata?
I will be very grateful for any help.
Regards,
Tiago
