Residual (shrunken) estimates can be computed along with a range of diagnostic information: A range of plots are available from the residual plots tab. The residuals can be standardised for ...

A residual-by-predicted plot is commonly used to diagnose nonlinearity or nonconstant error variance. It is also used to find outliers. A residual-by-predicted plot ...

Residuals are used to investigate the lack of fit of a model to a given subject. You can obtain martingale and deviance residuals for the Cox proportional hazards regression analysis by requesting ...

Residual plots and diagnostic techniques are important tools for examining the fit of a regression model. In the case of least squares fits, plots of residuals provide a visual assessment of the ...

The added variable plots proposed by Pregibon and Wang and the partial residual plots proposed by Pregibon and Landwehr and co-workers for generalized linear models have been found useful for ...
