Workspace Node: GLM Custom Design - Results - Residuals 1 Tab

In the GLM Custom Design node dialog box, under the Results heading, select the Residuals 1 tab to access the following options.

Element Name Description
Sample Select the respective option button in the Sample group box to specify which type of sample on which to base the predicted and residual statistics. You can display and plot predicted and residual values for all observations that were used to compute the current results (select Analysis), all observations that were not used to compute the current results, but have valid data for all predictor and dependent variables (select Cross-validation), all observations in both the analysis sample and the cross-validation sample (select Both - the data will be marked in the residual graphs), or all cases that have valid data for the predictor variables, but missing data for at least one dependent variable (select Pred). If these options are not available, no valid cases in the Prediction sample were found, and/or no Cross-validation sample was specified on the GLM Custom Design - Specifications - Options tab.
Dep. Variables Click this button to display a variable selection dialog box where you can select a subset of the dependent variables for the residual statistics. The predicted and residual values are computed for the dependent variables for the analysis, any within-subject (repeated measures) factors are ignored.
Show predicted and residual values Use the options in this group box to compute the desired predicted and residual statistics.
Spreadsheet predicted and residuals Select this check box to produce a spreadsheet of the observed, predicted, and residual values for each Dependent variable. The PRESS statistic will be given in the header of the spreadsheet. If the Cross-validation option button is selected in the Sample group box, only the observations in the Cross-validation sample will be shown (see above). If the Pred. option button is selected, only the observations in the Prediction sample will be shown.
Extended stats Select this check box to display predicted and residual statistics in addition to the basic observed, predicted, and residual values. If the Extended stats check box is selected, in addition to the predicted, observed, and residual values, Statistica computes the (default) 95% Prediction intervals and 95% Confidence limits, the Standardized predicted and Standardized residual score, the Leverage values, the Deleted residual and Studentized deleted residual scores, Mahalanobis and Cook distance scores, the DFFITS statistic, and the Standardized DFFITS statistic.
Separate spreadsheet for each dep. var. When there is more than a single dependent variable in the current analysis, by default the predicted and residual statistics for all variables are shown in a single spreadsheet, where consecutive dependent variables will occupy consecutive groups of columns. Select the Separate spreadsheet for each dep. var check box to display a separate spreadsheet for each dependent variable.
Sort obs by This drop-down list provides a number of options for ordering the cases or runs shown in the Predicted and residual values spreadsheet. From this list, you can select to sort the cases by Case numbers, by Observed, Predicted or Residual values, by Standard errors of predicted values, by Standardized predicted, Standardized residual or Studentized residual scores, by Leverage values, by Deleted residuals, Studentized deleted residuals, Mahalanobis distance, or Cook distance scores, by the DFFITS statistic, or by the Standardized DFFITS statistic. The default is to sort cases by Case numbers; note that if any other sort order is selected, the Separate Spreadsheet for each dep. var check box is automatically selected.
Predicted values Select this check box to produce a histogram of the predicted values.
Residuals Select this check box to produce a histogram of the residual values; the specific value that will be computed can be chosen via the Resids for default plots group box.
Resids for default plots In this group box, select the type of residual to be shown in the histograms, probability plots, and scatterplots of residuals. Instead of the standard Raw residuals (the default), you can choose Standardized residuals, Deleted residuals, Studentized residuals, or Studentized deleted residuals.
Probab. plots of resids Use the options in this group box to produce various plots of residual values for each Dependent variable; if the Cross-validation option button is selected in the Sample group box, only the observations in the Cross-validation sample will be shown; if the Pred. option button is selected, only the observations in the Prediction sample will be shown. To produce 2D or 3D plots of predicted or residual values against the observed values of other variables (e.g., predictor variables), select the GLM More Results - Residuals 2 tab.
Normal Select this check box to produce a normal probability plot of the residual values; the specific value that will be computed can be chosen via the Resids for default plots group box.
Half-normal Select this check box to produce a half-normal probability plot of the residual values; the specific value that will be computed can be chosen via the Resids for default plots group box; if the Plot absolute values check box is selected, the respective absolute residual values will be plotted.
Plot absolute values Select this check box to create the Half-normal probability plot based on the absolute residual values.
Detrended Select this check box to produce a detrended normal probability plot of the residual values; the specific value that will be computed can be chosen via the Resids for default plots group box.
Predicted and residuals Select this check box to produce a 2D scatterplot of the predicted versus residual values; the specific residual values that will be computed can be chosen via the Resids for default plots group box (see above).
Observed and predicted Select this check box to produce a 2D scatterplot of the observed versus predicted values.
Observed and residuals Select this check box to produce a 2D scatterplot of the observed versus residual values; the specific residual values that will be computed can be chosen via the Resids for default plots group box.
Residual and del. res. Select this check box to produce a 2D scatterplot of the residual values versus the deleted residuals.
Case no. & res Select this check box to produce a 2D scatterplot of the residual values versus the case numbers (of the observations in the plot). This plot is useful in order to detect any serial correlation between the residuals for consecutive observations.
