Hello David,
I'm not sure this is what you want, but the following code
clear
set obs 5000
scalar sig=70
scalar mu=0.15
scalar up=95
scalar low=45
g ///
wt=sig*invnorm((normal((up-mu)/sig)-normal((low-mu)/sig))*runiform()+normal((low-mu)/sig))+mu
su wt
generates a random variable tuncated at 'low' and 'up', and whose
*untruncated* distribution is normal with mean 'mu' and standard
deviation 'sig'
hope this helps,
Antoine

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.
