R: Simulates FD
SimulateFDR Documentation

Simulates FD

Description

A fractional Gaussian noise time series is simulated.

Usage

SimulateFD(n, d)

Arguments

n

length of time series

d

fractional difference parameter

Details

The FFT is used so it is most efficient if you select n to be a power of 2. Note, d=H-1/2.

Value

vector of length containing the simulated time series
