boundaries of the data set divided into the specified number of ranges.
For instance, @code{/NTILES=4} would cause quartiles to be reported.
+@cindex histogram
The HISTOGRAM subcommand causes the output to include a histogram for
each specified numeric variable. The X axis by default ranges from
the minimum to the maximum value observed in the data, but the MINIMUM
superimpose a normal curve on the histogram. Histograms are not
created for string variables.
+@cindex piechart
The PIECHART adds a pie chart for each variable to the data. Each
slice represents one value, with the size of the slice proportional to
the value's frequency. By default, all non-missing values are given
how many upper and lower extremes to show. The default number is 5.
+@cindex boxplot
+@cindex histogram
+@cindex npplot
The PLOT subcommand specifies which plots are to be produced if any.
+Available plots are HISTOGRAM, NPPLOT and BOXPLOT.
The COMPARE subcommand is only relevant if producing boxplots, and it is only
useful there is more than one dependent variable and at least one factor. If
[ /EXTRACTION=@{PC, PAF@}]
- [ /PRINT=[INITIAL] [EXTRACTION] [UNIVARIATE] [CORRELATION] [COVARIANCE] [DET] [SIG] [ALL] [DEFAULT] ]
+ [ /ROTATION=@{VARIMAX, EQUAMAX, QUARTIMAX, NOROTATE@}]
+
+ [ /PRINT=[INITIAL] [EXTRACTION] [ROTATION] [UNIVARIATE] [CORRELATION] [COVARIANCE] [DET] [SIG] [ALL] [DEFAULT] ]
[ /PLOT=[EIGEN] ]
If PC is specified, then Principal Components Analysis is used. If PAF is specified, then Principal Axis Factoring is
used. By default Principal Components Analysis will be used.
+The /ROTATION subcommand is used to specify the method by which the extracted solution will be rotated.
+Three methods are available: VARIMAX (which is the default), EQUAMAX, and QUARTIMAX.
+If don't want any rotation to be performed, the word NOROTATE will prevent the command from performing any
+rotation on the data. Oblique rotations are not supported.
+
The /METHOD subcommand should be used to determine whether the covariance matrix or the correlation matrix of the data is
to be analysed. By default, the correlation matrix is analysed.
Initial communalities and eigenvalues are printed.
@item EXTRACTION
Extracted communalities and eigenvalues are printed.
+@item ROTATION
+ Rotated communalities and eigenvalues are printed.
@item CORRELATION
The correlation matrix is printed.
@item COVARIANCE
