pairwise_intersection: Pairwise Probability of Intersection

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

Pairwise Probability of Intersection

Description

Calculates the pairwise probability of intersection. Also may be referred to as the joint probability, dot product similarity, or Russell Rao.

Usage

pairwise_intersection(data, cols, case_weights)

pairwise_joint(data, cols, case_weights)

pairwise_dot_product(data, cols, case_weights)

pairwise_russell_rao(data, cols, case_weights)

Arguments

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

Details

• Metric: Probability/Similarity

• Symmetrical: Yes

• Upper Limit: 1

• Lower Limit: 0

		B
		1	0
A	1	a	b
	0	c	d

Probability = a/N

Value

A matrix.

Examples

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