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

Pairwise Jaccard

Description

Calculates the pairwise Jaccard distance (or index).

Usage

pairwise_jaccard(data, cols, case_weights, metric = "dist")

Arguments

data	A data frame.
cols	Columns to analyze.
case_weights	An optional column of case weights.
metric	Metric to return, one of "dist" for Jaccard distance or "index" for Jaccard index Default is "dist".

Details

• Metric: Similarity or Dissimilarity

• Symmetrical: Yes

• Upper Limit: 1

• Lower Limit: 0

		B
		1	0
A	1	a	b
	0	c	d

Index = a/(a+b+c)
Distance = 1-Index

Value

A matrix.

Examples

res <- pairwise_jaccard(
    data = FoodSample,
    cols = Bisque:Turkey,
    metric = "dist"
)

print(res)

tidy(res)
