order_zip: Random Sampling of k-th Order Statistics from a Zero Inflated Poisson Distribution

Description

order_zip is used to obtain a random sample of the k-th order statistic from a Zero Inflated Poisson distribution and some associated quantities of interest.

Usage

order_zip(size, k, mu, sigma, n, p = 0.5, alpha = 0.05, ...)

Value

A list with a random sample of order statistics from a Zero Inflated Poisson Distribution, the value of its join probability density function evaluated in the random sample and and an approximate (1 - alpha) confidence interval for the population percentile p of the k-th order statistic.

Arguments

size

numeric, represents the size of the sample.

k

numeric, represents the K-th smallest value from a sample.

mu

numeric, represents the location parameter values.

sigma

numeric, represents scale parameter values.

n

numeric, represents the size of the sample to compute the order statistic from.

p

numeric, represents the 100p percentile for the distribution of the K-th order statistic. Default value is population median, p = 0.5.

alpha

numeric, (1 - alpha) represents the confidence of an interval for the population percentile p of the distribution of the k-th order statistic. Default value is 0.05.

...

represents others parameters of a Zero Inflated Poisson distribution.
