Random Sampling of k-th Order Statistics from a Gamma G I Distribution

Description

order_gammag1 is used to obtain a random sample of the k-th order statistic from a Gamma G I distribution and some associated quantities of interest.

Usage

order_gammag1(size, spec, a, k, n, p = 0.5, alpha = 0.05, ...)

Arguments

size

numeric, represents the size of the sample.

spec

character, represents an specific G distribution. Possible values "norm", "exp","lnorm","chisq".

a

numeric, represents the first shape parameter. Default value is 1.

k

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

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 median of the distribution of the k-th order statistic. Default value is 0.05.

...

represents others parameters of the G distribution.

Value

A list with a random sample of order statistics from a Gamma G I 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 distribution of the k-th order statistic.
