Categorical Bias Score (Kamath Eq 6.9)

Mean over template words of the variance over groups of log(p / prior). ddof = 0 is numpy's POPULATION variance.

Usage

morie_kamath_ch6_cbs_variance(W, A, p_a, p_prior, ddof = 0)

Arguments

W

Template words.

A

Social groups.

p_a, p_prior

|W| x |A| probability matrices.

ddof

Default 0.

Value

List with estimate, per_word, log_ratios.

Examples

morie_kamath_ch6_cbs_variance(c("w1", "w2"), c("g1", "g2"), matrix(c(0.6,
    0.3, 0.4, 0.7), 2), matrix(0.5, 2, 2))
