RAND and RANNOR parameters

deleted_user — Sat, 11 Dec 2010 05:15:42 GMT

Hi everyone,

I have a question. Is possible to generate a random numbers from a normal and T distribution with a given minimum and maximum possible values?

For example, given the following parameters: a minimum possible value of -15, a maximum of 40, a mean of 9.5, and a variance of 50...

What is a correct SAS code so I can obtain a pseudo-population with these parameters using both the RANNOR and the RAND functions?

In other words how can I obtain a pseudo-population whose parameters can be similar to the "real population" under study using RANNOR and RAND functions?

Thanks in advance for your help.

Caramel,

According to the following SUGI 31 paper, a macro exists that does what you are looking to accomplish:

http://www2.sas.com/proceedings/sugi31/198-31.pdf

However, I've been unable to obtain a copy of that macro. If anyone has it, I'd appreciate knowing how to find it.

Art,

It looks like the author is still at Sanofi-Aventis. Have you tried to e-mail or call her directly.

Someone else was looking for the macro on SAS-L a couple of years ago, but had no follow-up.

Doc,

Yes, I both saw that post and emailed the paper's author the same day as I posted my response to the current thread. If she resonds, I'll post the answer here.
