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
