Model Evaluation

Model selection plot: Check to plot the R2 values for the fitted and cross-validated models.

Response plot: Check to plot the fitted and cross-validated responses versus the actual responses.

Coefficient plot: Check to plot the unstandardized regression coefficients for each predictor.

Std coefficient plot: Check to plot the standardized regression coefficients for each predictor

Distance plot: Check to plot each observation's distance from the x-model and distance from the y-model.

Residual Analysis

Residual histogram: Check to display a histogram of the standardized residuals.

Residual normal plot: Check to display a normal probability plot of the standardized residuals.

Residual versus fit: Check to display standardized residuals versus the fitted values.

Residual versus leverage: Check to display standardized residuals versus the leverages.

Residual fourpack: Choose to display a layout of a histogram of standardized residuals, a normal plot of standardized residuals, a plot of standardized residuals versus fits, and a plot of standardized residuals versus leverages.

Component Evaluation

Score plot: Check to plot the x-scores of the first component versus the second component.

3D score plot: Check to plot the x-scores of the first component, second and third components.

Loading plot: Check to plot the x-loadings of the first component versus the second component.

Residual X plot: Check to display a line plot of the residual x-values.

Calculated X plot: Check to display a line plot of the fitted x-values.
