Technical Support Tip Choice of Continuous Response Distribution in Log-linked GLMs

When it comes to selecting a distribution to use when modeling a response, choosing a distribution that matches the observed mean-variance relationship is important. This note discusses and illustrates some tools for finding a suitable response distribution if it is not already known, including graphical and analytical methods.

Tips and Techniques for Using the Random-Number Generators in SAS

SAS 9.4M5 introduced new random-number generators (RNGs) and new subroutines that enable you to initialize, rewind, and use multiple random-number streams. This paper describes the new RNGs and provides tips and techniques for using random numbers effectively and efficiently in SAS. Applications of these techniques include statistical sampling, data simulation, Monte Carlo estimation, and random numbers for parallel computation.
