Hi, I think there is no difference in the estimations parts of two PROC. but some additional features are different. There are some major topics you should consider to check the appropriateness of your fitted model. One of them is zero inflated: http://www2.sas.com/proceedings/forum2008/322-2008.pdf There are also AIC,BIC and overdispersion problems: http://www2.sas.com/proceedings/forum2008/372-2008.pdf I think you should take consideration on your modeling strategy instead of choosing the more appropriate SAS procedure. In the following paper, you can find approximately all you need for answering your question: http://www2.sas.com/proceedings/sugi26/p247-26.pdf ... View more

Hi, You can use Box-Cox transformation using PROC TRANSREG in SAS to achieve normality.But by the summary statistics "log" may be a good transformation for your data. But one of the main problems with transformations are in the interpretations. Non - parametric methods will also be useful with lower power. But you can fit the model with Generalized Linear Models (GLM). The general method for modeling the length of stay in hospital has often GLM approach. check the following paper to know more about modeling length of stay: http://www.ncbi.nlm.nih.gov/pubmed/9630132 The full PDF of the above file is available by searching in Google. The SAS EG has the very good menu for GLM. ... View more
