Tests for Independence in Two-Way Contingency Tables Based on Canonical Analysis
Ming–Tan M. Tsai, Pranab Kumar Sen · Calcutta Statistical Association Bulletin · 1990
ABSTRACT: The canonical structure of a two‐way contingency table is emphasized to derive union‐intersection (Ul‐) tests for independence between two categorical variables. In this context, special attention has been paid to the so‐called step‐down procedure (which is a variant of the UI‐procedure Some properties of this procedure and computational algorithms are considered and a sequential way for identifying the adequate model is presented.
