order_beg: Random Sampling of k-th Order Statistics from a Beta Extended G Distribution

Description

order_beg is used to obtain a random sample of the k-th order statistic from a Beta Extended G distribution.

Usage

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

Value

A list with a random sample of order statistics from a Beta Extended 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.

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.
