Probabilistic Sensitivity Analysis in SAS for health economic evaluation- Markov model 3 health stat

[Gopi2]

HI SAS experts

I am looking for a standard SAS code for doing Probabilistic sensitivity analysis (PSA), which is mostly done using software like TreeAge/R. 

We are building a four state Markov model and want to do a PSA analysis in SAS. we are stuck at the part of of PSA where randomly selecting transitional probabilities around a health states while having more than two state is becoming tricky.

Any help would be appreciated. 

Warm regards
