GRM and GDA Syntax - Options for MBUILD

Click the MBUILD button on the GRM Analysis Syntax Editor - Specifications tab to display the Options for MBUILD dialog. This dialog contains options for the MBUILD keyword (see GRM Syntax for a list of all keywords; see also the GRM Analysis Syntax Editor dialog).

Element Name Description
Specifications Click a button in the Specifications group box to insert the respective option at the current cursor location in the Analysis syntax edit field on the GRM Analysis Syntax Editor dialog. The available specifications are described in detail below.
All Click the all button to insert the specification all into the Analysis syntax edit field, at the current location of the cursor. This option is used in conjunction with the MBUILD keyword; when all is specified, all effects in the DESIGN statement are automatically included in the model.
Forward Click the forward button to insert the specification forward into the Analysis syntax edit field, at the current location of the cursor. This option is used in conjunction with the MBUILD keyword; the forward option will cause STATISTICA to perform a forward stepwise regression analysis, where effects (see DESIGN), once entered into the model, cannot be removed in subsequent steps.
Backward Click the backward button to insert the specification backward into the Analysis syntax edit field, at the current location of the cursor. This option is used in conjunction with the MBUILD keyword; the backward option will cause STATISTICA to perform a backward stepwise regression analysis, where effects (see DESIGN), once removed from the model (see F2REMOVE, P2REMOVE, STEPCRIT) cannot be entered into the model in subsequent steps.
Fstepwise Click the fstepwise button to insert the specification fstepwise into the Analysis syntax edit field, at the current location of the cursor. This option is used in conjunction with the MBUILD keyword; the fstepwise option will cause STATISTICA to perform a forward stepwise regression analysis, where effects (see DESIGN), once entered into the model (see F1ENTER, P1ENTER, STEPCRIT), can be removed in subsequent steps if their contribution to the prediction of the dependent variable is not statistically significant, as defined by the F2REMOVE or the P2REMOVE keywords (see also the STEPCRIT keyword).
Bstepwise Click the bstepwise button to insert the specification bstepwise into the Analysis syntax edit field, at the current location of the cursor. This option is used in conjunction with the MBUILD keyword; the bstepwise option will cause STATISTICA to perform a backward stepwise regression analysis, where effects (see DESIGN), once removed from the model, can be reentered into the model in subsequent steps if their contribution to the prediction of the dependent variable is statistically significant, as defined by the F1ENTER or the P1ENTER keywords (see also the STEPCRIT keyword).
Bestsubset Click the bestsubset button to insert the specification bestsubset into the Analysis syntax edit field, at the current location of the cursor. This option is used in conjunction with the MBUILD keyword; the bestsubset option will cause STATISTICA to perform a comparisons of all possible subsets of effects (see DESIGN), and to find the best subset according to the specified criterion (see BESTCRIT) and given the respective subset sizes (see START and STOP).
