Goodman Kruskal's Tau for association between ordinal factors.

Calculates Goodman Kruskal's Tau coefficient for every factor variable pair in a dataset.

Usage

pair_gkTau(d, handle.na = TRUE, warnings = TRUE, ...)

Arguments

d: A dataframe
handle.na: ignored. Pairwise complete observations are used automatically.
warnings: If TRUE, generates a warning for datasets of one row, one column, or with constant variables.
...: other arguments

Value

A tibble of class pairwise with Goodman Kruskal's Tau for every factor variable pair, or NULL if there are not at least two factor variables

Details

The Goodman Kruskal's Tau coefficient is calculated using GoodmanKruskalTau function from the DescTools package. Assumes factor levels are in the given order. NAs are automatically handled by pairwise omit.

Examples
