GRM More Results

Click the More results button on the GRM Results dialog to display a GRM Results dialog with more options. This dialog contains eleven tabs: Summary, Means, Planned comps, Post-hoc, Assumptions, Profiler, Custom tests, Residuals 1, Residuals 2, Matrix, and Report. The tabs and options available in this dialog are almost identical to those described for STATISTICA General Linear Models; see the GLM More Results dialog (for an overview, see also Methods for analysis of variance). The differences pertain to the different types of analyses available in GRM, and not available in GLM, and vice versa; specifically:

• GRM contains options for reviewing the results for the model building computations (i.e., stepwise, best subset); see the Summary tab.
• Within-subject (repeated measures) designs cannot be analyzed in GRM, the options for displaying results for those effects (e.g., univariate and multivariate results for repeated measures effects; M transformation matrices, etc.) are not available.
• Designs with random effects cannot be analyzed in GRM, the options for displaying results for those effects (e.g., estimation of variance components, denominator synthesis; expected mean squares, etc.) are not available.

The Summary tab is used to produce summaries of the main results, for example, the summary of the model building computations (stepwise, best subset, etc.), ANOVA tables, parameter estimates, R-square, descriptive statistics, etc. The Means tab is used to compute (1) observed unweighted means, (2) observed weighted means, and (3) least squares (predicted) means; tables of marginal means can be displayed in spreadsheets or summarized in graphs. The Planned comps tab is used to test specific hypotheses about linear combinations of (least squares) means (planned comparisons). The Post-hoc tab is used to compute post-hoc comparisons between means. The Assumptions tab is used to test assumptions about the homogeneity of variances and covariances, distributions of variables and within-cell residuals and correlations, and the correlation between means and standard deviations or variances. The Profiler tab is used to compute and display desirability profiles for combinations of multiple variables. The Custom tests tab is used to select a list of effects from the current design and a custom error term for testing those effects. The Residuals 1 tab is used to compute predicted values and detailed residual statistics (e.g., residual, deleted residuals, Mahalanobis distance, leverage values, DFFITS values, etc.). The Residuals 2 tab is used to produce histograms, probability plots, and 2D and 3D scatterplots of predicted and residual values, as well as the observed values for any variable in the current data file. The Matrix tab is used to review various matrices involved in the computations of the main results, as well as detailed collinearity statistics and partial and semi-partial (or part) correlations. Finally, the Report tab is used to send results to a report.
