Description

Uses cut with breakpoints derived by getbw.

Usage

cutbw(x, k = NULL, min_n = NULL, warn = FALSE)

Arguments

x

A numeric variable.

k

The desired number of active bins. A bin is active if it contains at least min_n observations. The default is k <- 1 + 2*ceiling(log(N)/log(2)).

min_n

The minimum number of observations necessary for a bin to count as an active bin. Defaults to min_n = max(log(N/10)/log(10),1).

warn

Value

• An ordinal factor variable.
