qpois_mix: Quantile Function of a Poisson Mixture

In matheuscastro43/finiteMix: Finite Mixture Models

Quantile Function of a Poisson Mixture

Description

Gives the quantile function value of a univariate Poisson Mixture.

Usage

qpois_mix(p, pi, lambda, lower.tail = TRUE, log.p = FALSE)

Arguments

p	value or vector to apply on the quantile function.
pi	vector of mixture weights.
lambda	vector of (non-negative) parameters.
lower.tail	logical; if TRUE (default). probabilites are P[X ≤ x], otherwise P[X > x].
log.p	logical; if FALSE (default), probabilities are expected in p, otherwise log[probabilities] are expected.

Examples

## Quantile Function

## A value
qpois_mix(0.59, pi = c(0.6, 0.4), lambda = c(10, 18))
qpois_mix(0.59, pi = c(0.6, 0.4), lambda = c(10, 18), lower.tail = FALSE)

## A vector
qpois_mix(c(0.25, 0.50, 0.75), pi = c(0.6, 0.4), lambda = c(10, 18))
qpois_mix(c(0.25, 0.50, 0.75), pi = c(0.6, 0.4), lambda = c(10, 18), lower.tail = FALSE)
