Format of the Matrix Data File (RELIABILITY command)

  • The matrix data file includes two special variables: ROWTYPE_ and VARNAME_. Variable ROWTYPE_ is a short string variable having values N, MEAN, STDDEV, and CORR. Variable VARNAME_ is a short string variable whose values are the names of the variables used to form the correlation matrix.
  • When ROWTYPE_ is CORR, VARNAME_ gives the variable associated with that row of the correlation matrix.
  • The remaining variables in the matrix file are the variables used to form the correlation matrix.
