This menu can be used to display the fit of regression model. The graph shows the relationship
between the response variate and either one explanatory variate or one explanatory factor or one
of each.
Explanatory Variable
Specifies an explanatory variable to be used in the plot.
Grouping Factor
Specifies a grouping factor to be used in the plot.
Plot on linear predictor scale
By default for generalized linear models, the fitted relationship is plotted on the original scale, but
you can select this option to use the scale of the linear predictor. This is useful, for example,
if you want to check for potential non-linearity in the response.
Include Confidence Limits
When selected, includes confidence limits for the fitted relationship. The size of the interval
can be specified as a percentage in the space provided. This option is only available when
there no grouping factor has been supplied.
This menu allows you to choose which explanatory variate or factor, or both,
to display in the graph. Choose the variate from the Available Data box
(if you choose one, it must be one that has been fitted in the current model)
or choose a factor that is in the current model, or choose one of each.
Available Data
This lists data structures appropriate to the current input field. It lists
either factors for use in specifying grouping factor, or variates
for specifying the explanatory variate. The contents will change
as you move from one field to the next. Double-click on a name to copy
it to the current input field; alternatively, you can type the name
directly into the input field.
