# order_weibullg: Random Sampling of k-th Order Statistics from a Weibull G... In orders: Sampling from k-th Order Statistics of New Families of Distributions

## Description

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

## Usage

 `1` ```order_weibullg(size, spec, beta, c, k, n, 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 Kth smallest value from a sample. `n` numeric, represents the size of the sample to compute the order statistic from. `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 Weibull G Distribution, the value of its join probability density function evaluated in the random sample and a (1 - alpha) confidence interval for the population median of the distribution of the k-th order statistic..
