Well, you are asking for a normal, equivalent to
g wt2=rnormal(70, 10.5)
which could theoretically range from minus to plus infinity. Why do you want
it restricted? You can of course
drop if wt<45 | wt >95
and you would not lose too many observations, as 45 and 95 are far out in
the tails of N(70, 10.5)...

Subject: st: Generate a random variable with a range constraint
I apologise for what may be a fairly rudimentary question. I want to
generate a random variable (wt), n = 5000; as follows;
set obs 5000
set seed 1000
g wt = 70 * rnormal(1, 0.15)
However, wt also needs to be constrained as follows, 45 < wt < 95. I am
having difficulty incorporating the constraint into the generate function,
and would appreciate any help.
