Function h_kr

Description

Function h_{k,r}: R \to R is given by

h_{k,r} (x) = ∑_{j=0}^k (-1)^j {{k}\choose{j}} (x-rj)_+^{H-1/α}, \ \ \ x\in R

Usage

h_kr(k, r, x, H, alpha, l = 0)

Arguments

k

order of the increment, a natural number

r

difference step, a natural number

x

real number

H

Hurst parameter

alpha

self-similarity parameter of alpha stable random motion.

l

a value by which we shift x. Is used for computing function f_.+l and is passed to integrate function.
