Goodman Kruskal's Gamma for association between ordinal factors.

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

Usage

pair_gkGamma(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 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.
