For validation of any dataset, PROC COMPARE is your first choice. Not only are datasets compared but also listings and summary reports. For summary reports fromPROC REPORTfor example, plan to save results in output datasets. Use the power of PROC COMPARE to not only compare variable attributes,...
SAS/OR Software Consider more options and scenarios, determine the best allocation of resources and implement the best plans for accomplishing goals. Build models interactively & experiment with data Interactively build models, modify constraints or variables, and experiment easily with the effects of ch...

This article demonstrates how to use PROC GENMOD to perform a Poisson regression in SAS. There are different examples in the SAS documentation and in conference papers, but I chose this example because it uses two categorical explanatory variables. Therefore, the Poisson regression can be visualized...

In SAS, the easiest way to draw random sampling from data is to use PROC SURVEYSELECT or the SAMPLE function in SAS IML software. I have previously written about how to implement four common sampling schemes by using PROC SURVEYSELECT and the SAMPLE function. The DATA step in SAS is Read ...
In multiple logistic regression, a response variable can have several levels, such as low, medium and high, or 1, 2 and 3. Decision trees are classification models that partition data into subsets based on categories of input variables. This helps you understand someone's path of decisions. ...
