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.

  1. To produce a scatterplot of Standardized Deviance Residual by Predicted Value of the Linear Predictor, from the menus choose:

    Graphs > Chart Builder...

    Figure 1. Chart Builder
    Chart Builder
  2. In the Chart Builder, select the Scatter/Dot gallery and choose Simple Scatter.
  3. Select Standardized Deviance Residual as the y variable and Predicted Value of the Linear Predictor as the x variable.
  4. Click OK.

These selections produce the scatterplot.

There are a few points outside the general cloud which could be investigated further, but otherwise nothing suspicious in the plot.
