A Residual Diagnostic Plot
As an informal model check, look at a plot of the standardized deviance residuals versus the estimated linear predictors. These values were saved by the procedure to the active dataset.
- To produce a scatterplot of Standardized Deviance
Residual by Predicted Value of
the Linear Predictor, from the menus choose:
- In the Chart Builder, select the Scatter/Dot gallery and choose Simple Scatter.
- Select Standardized Deviance Residual as the y variable and Predicted Value of the Linear Predictor as the x variable.
- Click OK.
These selections produce the scatterplot.
The resulting scatterplot appears to not have any outlying points, with one possible cause for concern; the variability of the residuals appears to change with the value of the linear predictor.
