ODS Graphics |
Statistical procedures use ODS Graphics to create graphs as part of their output. ODS Graphics is described in detail in Chapter 21, Statistical Graphics Using ODS.
Before you create graphs, ODS Graphics must be enabled (for example, with the ODS GRAPHICS ON statement). For more information about enabling and disabling ODS Graphics, see the section Enabling and Disabling ODS Graphics in Chapter 21, Statistical Graphics Using ODS.
The overall appearance of graphs is controlled by ODS styles. Styles and other aspects of using ODS Graphics are discussed in the section A Primer on ODS Statistical Graphics in Chapter 21, Statistical Graphics Using ODS.
When ODS Graphics is enabled, the GAM procedure by default produces plots of the partial predictions for each nonparametric predictor in the model. Use the PLOTS option in the PROC GAM statement to control aspects of these plots.
PROC GAM assigns a name to each graph it creates by using ODS. You can use these names to reference the graphs when using ODS. The names are listed in Table 38.4.

SmoothingComponentPlot |

COMPONENTS(UNPACK) |
By default, partial prediction plots for each component are displayed in panels containing at most six plots. If you specify more than six smoothing components, multiple panels are used. Use the PLOTS(UNPACK) option in the PROC GAM statement to display these plots individually.
