pair_gkGamma(d, handle.na = TRUE, ...)

Arguments

d

A dataframe

handle.na

ignored. Pairwise complete observations are used automatically.

Value

A tibble of class pairwise with factor variable pairs and Goodman Kruskal's Gamma coefficient, or NULL if there are not at least two factor variables

Details

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