Loop with chi2 distribution in MATA

[Lina Anaya]

Hello, I'm trying to create 200 samples of a chi2 distribution with 20 degree freedom. And I stared with this:

set more off
clear mata
mata
x=1000
do
{
rchi2(x,1,20)
} while (x>=1000)
end

x is the number of observations and I decided that x starts in 1000, the problem with this is that the loops goes on forever and I don't know how tell it to does it just 200 times.

I'm totally new in stata mata
Thank you

You can do this in one line:

mata: A= rchi2(1000, 200, 20)
