Multiple Regression Cases Panel

The multiple regression model is unique among the statistical objects in having its own inspector (see Multiple Regression). To discuss the Cases panel in this inspector, we’ll use the example of trying to predict cost per hour (costph) for operating an airplane from speed and range. The multiple regression model is shown below.

With the model selected, choose Object | Inspect Linear Model to show its inspector.

The Cases panel should look very familiar. It differs from the collection’s Cases panel by having three additional attributes: one for predicted values, one for residuals, and one for standardized residuals. The formulas for these three attributes are created by the model and are not editable.

The attributes in this panel are available for use in graphs or summary tables.
