# Bartlett's Chi-square for Canonical Correlation

Jump to: navigation, search

Tests for independence between two sets of Number - Multi questions, containing ${\displaystyle p}$ and ${\displaystyle q}$ variables respectively. The test statistic is:

${\displaystyle V=-((n-1.5)-(p+q)/2.0)\sum _{i=1}^{m}\log(1-r_{i}^{2})}$

where

${\displaystyle n}$ is the Effective Sample Size,
${\displaystyle p\approx \Pr(\chi _{pq}^{2}\geq \Lambda )}$.
