Zero-inflated Poisson Quantile Function
qzip(p, lambda, pi, lower.tail = TRUE, log.p = FALSE)
vector of quantiles.
vector of (non-negative) means.
vector of (in \([0, 1]\)) zero-inflation parameters.
logical; if TRUE (default), probabilities are \(P[X <= x]\), otherwise, \(P[X > x]\).
logical; if TRUE, probabilities p. This doesn't affect pi.
A vector of quantiles, each of which coincide with the respective probability in p.
