order_loggammag2: Random Sampling of k-th Order Statistics from a Log Gamma G II Distribution

Description

order_loggammag2 is used to obtain a random sample of the k-th order statistic from a Log Gamma G II distribution.

Usage

order_loggammag2(size, spec, a, b, k, n, p = 0.5, alpha = 0.05, ...)

Value

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

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.
b: numeric, represents the second 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 percentile p of the distribution of the k-th order statistic. Default value is 0.05.
...: represents others parameters of the G distribution.
