dq {cdfquantreg}

The Family of Distributions

Description

Density function, distribution function, quantile function, and random generation of variates for a specified cdf-quantile distribution.

Usage

dq(x, mu, sigma, fd, sd)

rq(n, mu, sigma, fd, sd)

qq(p, mu, sigma, fd, sd)

pq(q, mu, sigma, fd, sd)

Arguments

x

vector of quantiles.

mu

vector of means.

sigma

vector of standard deviations.

fd

A string that specifies the parent distribution.

sd

A string that specifies the sub-family distribution.

n

Number of random samples.

p

vector of probabilities.

q

vector of quantiles.

Value

dq gives the density, rq generates random variates, qq gives the quantile function, and pq gives the cumulative density of specified distribution.

Examples

x <- rq(5, mu = 0.5, sigma = 1, 't2','t2'); x

dq(x, mu = 0.5, sigma = 1, 't2','t2')

qtil <- pq(x, mu = 0.5, sigma = 1, 't2','t2');qtil

qq(qtil , mu = 0.5, sigma = 1, 't2','t2')
