pKRTS: Cumulative probability distribution function of the Kim-Rachev tempered stable (KRTS) distribution

Description

The cumulative probability distribution function (CDF) of the Kim-Rachev tempered stable distribution.

Usage

pKRTS(
  q,
  alpha = NULL,
  kp = NULL,
  km = NULL,
  rp = NULL,
  rm = NULL,
  pp = NULL,
  pm = NULL,
  mu = NULL,
  theta = NULL,
  dens_method = "FFT",
  a = -40,
  b = 40,
  nf = 2048,
  ...
)

Value

As q is a numeric vector, the return value is also a numeric vector of probabilities.

Arguments

q

A vector of real numbers where the CF is evaluated.

alpha

Stability parameter. A real number between 0 and 2.

kp, km, rp, rm

Parameter of KR-distribution. A real number >0.

pp, pm

Parameter of KR-distribution. A real number >-alpha.

mu

A location parameter, any real number.

theta

Parameters stacked as a vector.

dens_method

Algorithm for numerical evaluation. Currently, only "FFT" available.

a

Starting point of FFT, if dens_method == "FFT". -40 by default.

b

Ending point of FFT, if dens_method == "FFT". 40 by default.

nf

Pieces the transformation is divided in. Limited to power-of-two size.

...

Possibility to modify stats::integrate().

Details

theta denotes the parameter vector (alpha, kp, km, rp, rm, pp. pm, mu)). Either provide the parameters individually OR provide theta. The function integrates the PDF numerically with integrate().
