Creating normally distriuted random variable given mean and standard deviation

[Karim Syed]

Hi all
I would like to create a random variable (X) with 100 observations. The variable should follow the normal distribution with mean 15 and standard deviation 5. Can anybody suggest a code for this? Thanks.

Karim:
you may want to try something along the following lines:

. drawnorm X, n(100) means(15) sds(5)


. kdensity X

Thanks a lot.

Dear Carlo
Is it possible to have the variable X in a certain range say between 0 and 50, where 0 is the minimum and 50 is the maximum observation for X?

Karim:
not to my knowledge.
In order to feed -drawnorm- you should recalculate mean and sd according to the range you're interested in.

How does the request in #4 for prespecified bounds square with the request in #1 for a normal distribution? A normal distribution in principle has tails out to either infinity. Naturally you won't see that in samples.
