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

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.
