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

Description

order_weibullg is used to obtain a random sample of the k-th order statistic from a Weibull G distribution.

Usage

order_weibullg(size, spec, beta, c, k, n, p = 0.5, alpha = 0.02, ...)

Arguments

size	numeric, represents the size of the sample.
spec	character, represents an specific G distribution. Possible values "norm", "exp","lnorm","chisq".
beta	numeric, represents the scale parameter. Default value is 1.
c	numeric, represents the 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.

Value

A list with a random sample of order statistics from a Weibull G 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.
