9.6.2.3 Residual Analysis Report

The first page of the Residual Analysis Report for this case
study is shown in Figure 9-14.  Examining this report
confirms that TEST 2 (visual inspection of the predicted
versus the actual data) passed acceptably.  Comparison of
CTLCPUTM and PREDICTED CTLCPUTM shows a very close agreement
between the actual and predicted values.

The independent variable names for this model are listed
under the column INDEPENDENT-ELEMENT NAME, which indicates
that this model is the two-variable model.
