The MVPDIAGNOSE Procedure
CONTRIBUTIONPANEL Statement
CONTRIBUTIONPANEL < / options> ;
The CONTRIBUTIONPANEL statement displays a paneled layout of the contribution plots for each observation in the input data set, up to a maximum specified by the MAXNPLOTS= option. Individual contribution plots are displayed in panels from left to right and top to bottom, and they are identified by TIME variable values or observation numbers. You can use the CONTRIBUTIONPLOT statement to display each contribution plot as a separate graph.
Table 11.1 summarizes the options available in the CONTRIBUTIONPANEL statement.

You can specify the following options in the CONTRIBUTIONPANEL statement. The section Common Plot Statement Options describes additional options that are available in all plot statements.
- MAXNPLOTS=n
-
specifies the maximum number of contribution plots to be produced by the CONTRIBUTIONPANEL statement. The number of plots that are 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. The default is 50.
- MAXNVARS=n
-
specifies the maximum number of process variable contributions to be displayed in the paneled layout. The magnitudes for each contribution are summed over the observations to be plotted, and the n contributions with the greatest total magnitudes are displayed. Therefore each plot displays contributions for the same process variables. By default, all contributions are displayed.
- NCOLS=c
-
specifies the number of columns in the panel layout. See the section Paneled Contribution Plot Layouts for a description of how the default numbers of columns and rows are calculated.
- NROWS=r
-
specifies the number of rows in the panel layout. See the section Paneled Contribution Plot Layouts for a description of how the default numbers of columns and rows are calculated.
- TYPE=SPE | TSQUARE
-
specifies the type of contribution plots displayed. If you specify TYPE=SPE, the contribution plots are based on the SPE statistics; if you specify TYPE=TSQUARE, the contribution plots are based on the
statistics. You must specify a LOADINGS= data set to create contribution plots. By default, TYPE=TSQUARE if a LOADINGS= data set is provided and TYPE=SPE otherwise.
