In Rfast: A Collection of Efficient and Extremely Fast R Functions

Column-wise Yule's Y (coefficient of colligation)

Description

Column-wise Yule's Y (coefficient of colligation).

Usage

col.yule(x, y = NULL, ina)

Arguments

x	A matrix with 0 and 1. Every column refers to a different sample or variable.
y	A second matrix, of the same dimensions as x, with 0 and 1. Every column refers to a different sample or variable.
ina	If y is NULL, ina must be specified. This is a numeric vector with 1s and 2s, indicating the group of each row.

Details

Yule's coefficient of colligation is calculated for every column.

Value

A vector with Yule's Y, one for every column of x is returned.
