Missing values cause "Matrices Do Not Conform" error or incorrect values or both from the RsquareV macro


If the input data set contains missing values, the RsquareV macro might produce the following error when using SAS/IML to do its computations:

  ERROR: (execution) Matrices do not conform to the operation.

If SAS/IML is not available, then the macro uses an alternative analytical method that can result in incorrect values of the R2v statistics.

To avoid the problem, install and use Version 1.2 of the RsquareV macro. Alternatively, remove all observations with missing values in the RESPONSE=, PFULL=, or PSUB= variables from the input data set.
