Polyserial correlation

Calculates Polyserial correlation using for every factor-numeric variable pair in a dataset.

Usage

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

Arguments

d

A dataframe

handle.na

ignored. Pairwise complete observations are used automatically.

...

other arguments

Value

A tibble of class pairwise with polyserial correlation for factor-numeric pairs, or NULL if there are not at least one such pair.

Details

The polyserial correlation is calculated using the polyserial function from the polycor package, and assumes factor levels are in the given order. NAs are automatically handled by pairwise omit.
