Multivariate Regression R-Square Ranking Report
The R-Square Ranking report provides you with an overview of the results of all of the forecasts performed during this forecasting run.
rm
The report is presented in ascending R- Square sequence and gives the r-square, f-statistic, and p- values for the statistical model generated. The r-squares and p-values for the individual variables in the best model are also provided.
If either the r-square or p-value for the run exceeds the thresholds set for the report, the Warning Flag column will be set to show which threshold was exceeded. If the flag is set to RS-WARN then the r-square for this particular forecast was below the threshold; if the flag is set to P-WARN then one of the p-values for one of the variables in the model was exceeded. If both thresholds are exceeded then the RS-WARN takes precedence.
The other fields on this report correspond to the equivalent values found on the other reports associated with the forecasting process.
You can use the R-Square Ranking report to review the results of all your forecasts and to indicate whether you have to take further action. For example, review the Model Analysis report or the Residual Analysis report to see what might be affecting these results. We recommend that for critical workloads you review these other reports regardless of whether they are flagged on this report.
