Abstract

A Pearson residual is defined as the residual between actual values and expected ones of each cell in a contingency table. This paper shows that this residual is represented as linear sum of determinants of 2×2, which suggests that the geometrical nature of the residuals can be viewed from grasmmanian algebra.
