herlang: Create HErlang distribution

Description

Create an instance of Hyper-Erlang distribution

Usage

herlang(
  size,
  shape,
  mixrate = rep(1/length(shape), length(shape)),
  rate = rep(1, length(shape))
)

Value

An instance of HErlang

Arguments

size

An integer of the number of phases

shape

A vector of shape parameters

mixrate

A vector of initial probability (mixrate)

rate

A vector of rate parameters

Examples

## create a hyper Erlang consisting of two Erlang
## with shape parameters 2 and 3.
(param1 <- herlang(shape=c(2,3)))

## create a hyper Erlang with specific parameters
(param2 <- herlang(shape=c(2,3), mixrate=c(0.3,0.7), rate=c(1.0,10.0)))

## convert to a general PH
as.gph(param2)

## p.d.f. for 0, 0.1, ..., 1
(dphase(x=seq(0, 1, 0.1), ph=param2))

## c.d.f. for 0, 0.1, ..., 1
(pphase(q=seq(0, 1, 0.1), ph=param2))

## generate 10 samples
(rphase(n=10, ph=param2))
