SPLIT Specification (MATRIX-END MATRIX command)
To write a matrix-format data file with split-file
groups, you must use the SPLIT specification to provide a row matrix containing the values of each
of the split-file variables for the matrix expression being written
by the current MSAVE statement.
- The split vector must have the same number of columns
as there are split-file variables in the matrix data file being written.
You can use a scalar when there is only one split-file variable. For
example,
SPLIT=3indicates that the matrix data being written are for the value 3 of the split-file variable. - The values of the split vector are written to the matrix-format data file as values of the split-file variable(s).
- To create a complete matrix-format data file with
split-file variables, you must execute
MSAVEstatements for every combination of values of the split-file variables. (If factor variables are present, you must executeMSAVEstatements for every combination of factor codes within every combination of values of the split-file variables.)
