PH_functions: The Univariate Continuous Phase-Type Distribution

In rivasiker/PhaseTypeR: General-Purpose Phase-Type Functions

The Univariate Continuous Phase-Type Distribution

Description

Density, distribution function, quantile function and random generation for the univariate continuous phase-type distribution.

Usage

dPH(x, obj)

qPH(p, obj)

pPH(q, obj)

rPH(n, obj)

rFullPH(obj)

Arguments

x, q	vector of quantiles.
obj	an object of class cont_phase_type.
p	vector of probabilities.
n	number of observations. If length(n) > 1, the length is taken to be the number required.

Value

dPH gives the density, pPH gives the distribution function, qPH gives the quantile function, and rPH generates random deviates. rFullPH returns the full path of a random draw from the distribution.

The length of the result is determined by n for rPH, and is the maximum of the lengths of the numerical arguments for the other functions.

The numerical arguments other than n are recycled to the length of the result. Only the first elements of the logical arguments are used.

Functions

• dPH(): Density function for the univariate continuous phase-type distribution.

• qPH(): Quantile function for the univariate continuous phase-type distribution.

• pPH(): Distribution function for the univariate continuous phase-type distribution.

• rPH(): Random number generator for the univariate continuous phase-type distribution.

• rFullPH(): Simulation of the full path for the univariate continuous phase-type distribution.
