## Displayed Output

The PRINCOMP procedure displays the following items if the
DATA= data set is not TYPE=CORR, TYPE=COV, TYPE=SSCP,
TYPE=UCORR, or TYPE=UCOV:

- Simple Statistics, including the Mean and
Std (standard deviation) for each variable.
If you specify the NOINT option, the uncorrected
standard deviation (UStD) is displayed.

- the Correlation or, if you specify the COV option,
the Covariance Matrix

The PRINCOMP procedure displays the following items
if you use the PARTIAL statement.
- Regression Statistics, giving the
*R*-square and RMSE
(root mean square error) for each VAR variable as
predicted by the PARTIAL variables (not shown)
- Standardized Regression Coefficients or, if you specify the COV
option, Regression Coefficients for predicting
the VAR variables from the PARTIAL variables (not shown)

- the Partial Correlation Matrix or, if you specify the COV option,
the Partial Covariance Matrix (not shown)

The PRINCOMP procedure displays the following item if you specify the COV option:
The PRINCOMP procedure displays the following items unless
you specify the NOPRINT option:
- Eigenvalues of the correlation or covariance matrix,
as well as the Difference between successive eigenvalues,
the Proportion of variance explained by each eigenvalue,
and the Cumulative proportion of variance explained

- the Eigenvectors
