gmsnburr {neodistr}

GMSNBurr distribution

Description

To calculate density function, distribution funcion, quantile function, and build data from random generator function for the GMSNBurr Distribution.

Usage

dgmsnburr(x, mu = 0, sigma = 1, alpha = 1, beta = 1, log = FALSE)

pgmsnburr(
  q,
  mu = 0,
  sigma = 1,
  alpha = 1,
  beta = 1,
  lower.tail = TRUE,
  log.p = FALSE
)

qgmsnburr(
  p,
  mu = 0,
  sigma = 1,
  alpha = 1,
  beta = 1,
  lower.tail = TRUE,
  log.p = FALSE
)

rgmsnburr(n, mu = 0, sigma = 1, alpha = 1, beta = 1)

Arguments

x, q

vector of quantiles.

mu

a location parameter.

sigma

a scale parameter.

alpha

a shape parameter.

beta

a shape parameter.

log, log.p

logical; if TRUE, probabilities p are given as log(p) The default value of this parameter is FALSE.

lower.tail

logical;if TRUE (default), probabilities are P\left[ X\leq x\right], otherwise, P\left[ X>x\right] .

p

vectors of probabilities.

n

number of observations.

Details

GMSNBurr Distribution

The GMSNBurr distribution with parameters \mu, \sigma,\alpha, and \beta has density:

f(x |\mu,\sigma,\alpha,\beta) = {\frac{\omega}{{B(\alpha,\beta)}\sigma}}{{\left(\frac{\beta}{\alpha}\right)}^\beta} {{\exp{\left(-\beta \omega {\left(\frac{x-\mu}{\sigma}\right)}\right)} {{\left(1+{\frac{\beta}{\alpha}} {\exp{\left(-\omega {\left(\frac{x-\mu}{\sigma}\right)}\right)}}\right)}^{-(\alpha+\beta)}}}}

where -\infty<x<\infty, -\infty<\mu<\infty, \sigma>0, \alpha>0, \beta>0 and \omega = {\frac{B(\alpha,\beta)}{\sqrt{2\pi}}}{{\left(1+{\frac{\beta}{\alpha}}\right)}^{\alpha+\beta}}{\left(\frac{\beta}{\alpha}\right)}^{-\beta}

Value

dgmsnburr gives the density , pgmasnburr gives the distribution function, qgmsnburr gives quantiles function, rgmsnburr generates random numbers.
