u_scaleR Documentation

Rank uniformization

Description

Compute rank uniformization for a numeric array. First replace each value by its rank. Average rank for ties are used to conserve the number of unique values of discrete quantities. Second, uniformize ranks to the scale ⁠[1/(2S), 1-1/(2S)]⁠, where S is the number of values.

Usage

u_scale(x, c = 3/8)

Arguments

x

(numeric) A scalar, vector, matrix, or array of values.

c

(numeric) Fractional offset used in the back-transformation of ranks. Defaults to 3/8.

Value

A numeric array of uniformized values with the same size and dimension as the input.
