HOMALS 733<br />

HOMALS VARIABLES COLA1 (4) COLA2 (4) COLA3 (4) COLA4 (2)<br />

/ANALYSIS COLA1 COLA2 COLA3 COLA4<br />

/PLOT OBJECT(COLA4).<br />

• Four variables are included in the analysis.<br />

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

whose COLA4 value is not 1 or 2, is labeled 3 (or the value label for category 3, if supplied).<br />

Example<br />

HOMALS VARIABLES COLA1 (4) COLA2 (4) COLA3 (4) COLA4 (2)<br />

/ANALYSIS COLA1 COLA2 COLA3<br />

/PLOT OBJECT(COLA4).<br />

• Three variables are included in the analysis.<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 produced<br />

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

Example<br />

HOMALS 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 />

HOMALS 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<br />

indicates that all possible pairs up to the second value should be plotted, so QUANT plots
