ASTATUS procedure

Provides information about the settings of ANOVA models and variates (R.W. Payne).

Option

PRINT = strings

Controls printed output (y, model); default mode

Parameters

Y = pointers

Pointer of length 1 to save the identifier of the y-variate of the most recent ANOVA or that used to form INSAVE

TREATMENTSTRUCTURE = formulae

Saves the current setting of TREATMENTSTRUCTURE or the setting used to form INSAVE

BLOCKSTRUCTURE = formulae

Saves the current setting of BLOCKSTRUCTURE or the setting used to form INSAVE

COVARIATE = pointers

Saves the current COVARIATE setting or the setting used to form INSAVE

SAVE = asave structures

Saves the save structure from the most recent ANOVA

INSAVE = asave structures

Provides a save structure from which to save Y, TREATMENTSTRUCTURE, BLOCKSTRUCTURE and COVARIATE; default * uses the current settings

Description

ASTATUS allows information to be printed and saved about the model settings and other information involved in an ANOVA analysis.

By default ASTATUS prints the current settings defined by the directives TREATMENTSTRUCTURE, BLOCKSTRUCTURE and COVARIATE. This is governed by the default setting, model, of the PRINT option. The other setting y prints the name of the y-variate from the most recent ANOVA. Alternatively, if the INSAVE parameter is set to the save structure from an ANOVA analysis, the y-variate and model settings will be those used to form the save structure.

If the INSAVE parameter is not set, the Y parameter can be used to save the identifier of the y-variate most recently analysed by ANOVA, in a pointer of length one. The TREATMENTSTRUCTURE parameter saves the current setting defined by the TREATMENTSTRUCTURE directive (in a formula structure), and the BLOCKSTRUCTURE parameter similarly saves the current setting defined by the BLOCKSTRUCTURE directive. The COVARIATE parameter saves the current setting defined by the COVARIATE directive (in a pointer). Alternatively, if INSAVE is set to an ANOVA save structure, the parameters Y, TREATMENTSTRUCTURE, BLOCKSTRUCTURE and COVARIATE save the settings used to form INSAVE.

The SAVE parameter saves the save structure from the most recent ANOVA (regardless of the setting of INSAVE).

Option: PRINT.

Parameters: Y, TREATMENTSTRUCTURE, BLOCKSTRUCTURE, COVARIATE, SAVE, INSAVE.

Method

ASTATUS uses the GET directive to obtain the current settings of BLOCKSTRUCTURE, TREATMENTSTUCTURE and COVARIATE, and the save structure from the most recent ANOVA. It uses specialist knowledge of the ANOVA save structure to obtain information from an ANOVA save structure input using the INSAVE option.
