The following list describes each output variable and indicates how it is named. represents the name of the response variable.

Predicted values

adds predicted values. The variable is named PolyP_.

Confidence limits for means

adds 95% confidence limits for the expected value (mean). The variables are named PolyLclm_ and PolyUclm_.

Prediction limits for individuals

adds 95% confidence limits for an individual prediction. The variables are named PolyLcli_ and PolyUcli_.

Raw residuals

adds residuals, calculated as observed minus predicted values. The variable is named PolyR_.
