Cramer_V: Cramer V Statistic for Strength of Association
Description
Computes Cramer V to assess the strength of association between two categorical variables.
Usage
Cramer_V(a, b)
Value
A numeric value between 0 and 1 representing the strength of association (Cramer V).
Arguments
a
A numeric or categorical vector (used for rows in the contingency table).
b
A numeric or categorical vector (used for columns in the contingency table).
Details
This measure is derived from the Chi-squared statistic and a contingency table.
Both parameters can be a categorical variable, allowing flexibility in working with labelled data.
