STATISTICAL ANALYSIS OF SETS OF CONGENERIC TESTS*

ABSTRACT Various models for sets of congeneric tests are considered, including models appropriate for the analysis of multitrait‐multimethod data. All models are illustrated with real data. The special cases when two or more tests within a set are tau‐equivalent or parallel are also considered. All data analyses are done within the framework of a general model by Jo̎reskog (1969b).
