SAVE Subcommand<br />

• OBJECT requests a plot of the object scores labeled with the values of COLA4, a variable<br />

not included in the analysis. Objects are labeled using all values of COLA4.<br />

In addition to the plot keywords, the following can be specified:<br />

NDIM Dimension pairs to be plotted. NDIM is followed by a pair of values in parentheses.<br />

If NDIM is not specified, plots are produced for dimension 1 versus dimension 2.<br />

• The first value indicates the dimension that is plotted against all higher dimensions. This<br />

value can be any integer from 1 to the number of dimensions minus 1.<br />

• The second value indicates the highest dimension to be used in plotting the dimension<br />

pairs. This value can be any integer from 2 to the number of dimensions.<br />

• Keyword ALL can be used instead of the first value to indicate that all dimensions are<br />

paired with higher dimensions.<br />

• Keyword MAX can be used instead of the second value to indicate that plots should be<br />

produced up to, and including, the highest dimension fit by the procedure.<br />

Example<br />

PRINCALS COLA1 COLA2 COLA3 COLA4 (4)<br />

/PLOT NDIM(1,3) QUANT(5).<br />

• The NDIM(1,3) specification indicates that plots should be produced for two dimension<br />

pairs—dimension 1 versus dimension 2 and dimension 1 versus dimension 3.<br />

• QUANT requests plots of the category quantifications. The (5) specification indicates that<br />

the first five characters of the value labels are to be used on the plots.<br />

Example<br />

PRINCALS COLA1 COLA2 COLA3 COLA4 (4)<br />

/PLOT NDIM(ALL,3) QUANT(5).<br />

• This plot is the same as above except for the ALL specification following NDIM. This indicates<br />

that all possible pairs up to the second value should be plotted, so QUANT plots<br />

will be produced for dimension 1 versus dimension 2, dimension 2 versus dimension 3,<br />

and dimension 1 versus dimension 3.<br />

SAVE lets you add variables containing the object scores computed by PRINCALS to the<br />

working data file.<br />

• If SAVE is not specified, object scores are not added to the working data file.<br />

• A variable rootname can be specified on the SAVE subcommand to which PRINCALS adds<br />

the number of the dimension. Only one rootname can be specified, and it can contain up<br />

to six characters.<br />

• If a rootname is not specified, unique variable names are automatically generated. The<br />

variable names are PRIn_m, where n is a dimension number and m is a set number. If three<br />

dimensions are saved, the first set of names is PRI1_1, PRI2_1, and PRI3_1. If another
