CONTRIBUTIONPLOT Statement

CONTRIBUTIONPLOT < / options> ;
The CONTRIBUTIONPLOT statement produces a contribution plot for each observation in the input data set, up to a maximum specified by the MAXNPLOTS= option.
You can specify the following options after a slash (/):
MAXNPLOTS=n

specifies the maximum number, n, of contribution plots produced by the CONTRIBUTIONPLOT statement. The number of plots produced is the minimum of n and the number of observations in the input data set. When n is less than the number of observations, contribution plots are produced for the first n observations.

MAXNVARS=n

specifies that only the n contributions with the greatest magnitudes be displayed in the plots. For each plot, the n variables that contribute the most to that plot are displayed. By default, all variable contributions are displayed.

TYPE=SPE | TSQUARE

specifies the type of contribution plot that is created. The option TYPE=TSQUARE specifies that the contribution plots are based on the statistics. The option TYPE=SPE specifies that the contribution plots are based on the SPE statistics. By default, TYPE=TSQUARE if the LOADINGS= data set is provided, otherwise TYPE=SPE. It is possible to have more than one CONTRIBUTIONPLOT statement.
