Pearson contingency coefficient C (Gibbons Ch 14.2.1)

C = sqrt(chi^2 / (chi^2 + n)). Also reports Cramer's V and the maximum attainable C = sqrt((min(r,c)-1)/min(r,c)).

Usage

morie_contingency_coefficient(x)

Arguments

x

A 2-D contingency table of counts.

Value

Named list: statistic (C), morie_cramers_v, chi2, p_value, df, max_C, n.

Examples
