pairwise_phi: Pairwise Pearson's Phi

In ttrodrigz/onezero: Analysis tools for binary (0/1) data

Pairwise Pearson's Phi

Description

Calculates the pairwise Pearson's Phi coefficient of correlation.

Usage

pairwise_phi(data, cols, case_weights)

Arguments

data	A data frame.
cols	Columns to analyze.
case_weights	An optional column of case weights.

Details

• Metric: Correlation/similarity

• Symmetrical: Yes

• Upper Limit: 1

• Lower Limit: -1

		B
		1	0
A	1	a	b
	0	c	d

Phi = ((a*d)-(c*b))/sqrt((a+c)*(c+d)*(a+b)*(b+d))

Value

A matrix.

Examples

res <- pairwise_phi(
    data = FoodSample,
    cols = Bisque:Turkey
)

print(res)

tidy(res)
