Split Files (REGRESSION command)

  • When split-file processing is in effect, the first variables in the matrix data file are the split variables, followed by ROWTYPE_, the independent variable, VARNAME_, and the dependent variables.
  • A full set of matrix materials is written for each subgroup defined by the split variable(s).
  • A split variable cannot have the same variable name as any other variable written to the matrix data file.
  • If a split file is in effect when a matrix is written, the same split file must be in effect when that matrix is read.
