The OUTMODEL= data set should not be modified before its use as an INMODEL= data set.

Hello,

Anybody have any more clarification about this comment which I read in the documentation. This is in reference to Proc Logistic. https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=statug&docsetTarget=statu...

What kind of modifications is it referring to? What is ok and not ok?

Some of the modeling procedures produce data set with very particular structures. If you are not intimately aware of what the structure is and how it is used for in model then no changes would be a good idea.

Changes to values to any variables or their names would almost certainly invalidate any result when used as Inmodel.
