The matrix materials that PARTIAL CORR writes can be used by subsequent PARTIAL CORR procedures or by other procedures
that read correlation-type matrices.
In addition to the partial correlation coefficients,
the matrix materials that PARTIAL CORR writes include the mean, standard deviation, and number of cases
that are used to compute each coefficient (see Format of the Matrix Data File (PARTIAL CORR command) for a description of the file) . If PARTIAL CORR reads matrix data and then writes matrix materials based on those
data, the matrix data file that it writes will not include means and
standard deviations.
PARTIAL CORR writes a full square matrix for the analysis that is specified on
the VARIABLES subcommand (or
the analysis list if keyword VARIABLES is omitted). No matrix is written for subsequent variable lists.
Any documents that are contained in the active dataset
are not transferred to the matrix file.
