Zero-inflated Tail-adjusted Beta Quantile Function

Zero-inflated Tail-adjusted Beta Quantile Function

qzitab(p, mu, phi, delta, pi, lower.tail = TRUE, log.p = FALSE)

Arguments

p

vector of quantiles.

mu

mean/s in (0, 1) for the beta distribution.

phi

dispersion parameter (positive) for the beta distribution.

delta

rounding parameter in (0, 0.5) for the tail adjustment.

pi

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

lower.tail

logical; if TRUE (default), probabilities are \(P[X <= x]\), otherwise, \(P[X > x]\).

log.p

logical; if TRUE, probabilities p. This doesn't affect pi.

Value

A vector of quantiles, each of which coincide with the respective probability in p.
