ACKEEP procedure

Saves information from an analysis by ACANONICAL (C.J. Brien).

Options

COMBINEDPROJECTIONSET = pointer Saves the projector pointers that produce the orthogonal decomposition
EFFICIENCYFACTORS = pointer Saves the canonical efficiency factors
ECRITERIA = pointer Saves the unadjusted efficiency criteria
ADJECRITERIA = pointer Saves the adjusted efficiency criteria
ADJDF = pointer Saves the adjusted degrees of freedom
SAVE = pointer Information saved from ACANONICAL; if this is not set, the information is saved from the most recent ACANONICAL analysis

No parameters

Description

ACKEEP lets you save information from an analysis by the ACANONICAL procedure.

ACANONICAL determines the decomposition of the sample space for a design, using an analysis of the canonical relationships between the projectors derived from two or more model formulae. It has parameters that allow you to save the information at the time of the analysis. ACKEEP provides a way to save information afterwards. It has options with the same names as the COMBINEDPROJECTIONSET, EFFICIENCYFACTORS, ECRITERIA, ADJECRITERIA and ADJDF parameters of ACANONICAL, which save the information in exactly the same way; see ACANONICAL for details.

By default, the information is saved from the most recent ACANONICAL analysis. The SAVE option of ACKEEP lets you save information from an earlier analysis, by setting it to a pointer saved earlier using the SAVE parameter of ACANONICAL.

Options: COMBINEDPROJECTIONSET, EFFICIENCYFACTORS, ECRITERIA, ADJECRITERIA, ADJDF, SAVE.

Parameters: none.
