twoway (version 0.6.3)

Analysis of Two-Way Tables

Description

Carries out analyses of two-way tables with one observation per cell, together with graphical displays for an additive fit and a diagnostic plot for removable 'non-additivity' via a power transformation of the response. It implements Tukey's Exploratory Data Analysis (1973) methods, including a 1-degree-of-freedom test for row*column 'non-additivity', linear in the row and column effects.
