Zero-inflated Poisson Probability Mass Function

dzip(x, lambda, pi, log = FALSE)

Arguments

x

vector of (non-negative integer) values.

lambda

vector of (non-negative) means.

pi

vector of (real lying in [0, 1]) zero-inflation parameters.

log

logical; if TRUE, probabilities, p, are given as log(p).

Value

The (log) probability mass at x, given lambda and pi.
