Usage

jaccard.ev(x, y, px = NULL, py = NULL)

Arguments

x

a binary vector (e.g., fingerprint)

y

a binary vector (e.g., fingerprint)

px

probability of successes in x (optional)

py

probability of successes in y (optional)

Value

jaccard.ev returns an expected value.

Examples

set.seed(1234)
x = rbinom(100,1,.5)
y = rbinom(100,1,.5)
jaccard.ev(x,y)
