Graph of fitted model

Use this 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.

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 a name to copy it to the current input field or type the name.

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. Use this to choose which explanatory variate or factor, or both, to display in the graph. Choose the variate from the Available data list (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.
