Collapse
A collapse command summarizes data using aggregation functions applied to data that may be grouped by one or more variables. The resulting summary data is represented in a new dataset. See the collapse functions in the Function Library.
The details of implementation of caseWise and columnWise exclusion vary in each statistical package. The source language is indicated in this property for reference.
