Computes Quantiles
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.
