QuantileGpois: Computes Quantiles

In RNGforGPD: Random Number Generation for Generalized Poisson Distribution

Description

QuantileGpois computes the quantile for the generalized Poisson distribution for specified values of percentile, rate, and dispersion parameters.

Usage

QuantileGpois(p, theta, lambda, details = FALSE)

Arguments

p	percentile of the generalized Poisson distribution, p should be between 0 and 1.
theta	the rate parameter in the generalized Poisson distribution. It has to be a positive number.
lambda	the dispersion parameter in the generalized Poisson distribution. It has to be less than 1. For lambda < 0, lambda must be greater than or equal to -theta/4.
details	index of whether to display the probabilities and cumulative probabilities. Default is set to FALSE.

Value

Quantile of the specified distribution if the parameter details is set to FALSE, detailed information of probabilities and cumulative probabilities otherwise.
