I am working on models to predict hospital readmission. The data were arranged by admissions (claim ID) with a flag to indicate whether there was readmission followed. A member (person) could have multiple admissions, which meant one member ID could correspond to multiple claim IDs. How do I take this repeated measure into account in SAS EM? I did not find any place I could define repeated variable in regression, decision tree or neural network. I suspect probably variable role in SAS EM could clarify this? But how? When I raised this question in one SAS user group meeting, people from bank system told me that my scenario is equivalent to theirs in which they have person level data as well as account level data (one person could have multiple accounts). But they could not answer my question. Does anyone have any experience? Thanks. ... View more
