The FGN time series is an example of a time series exhibiting long-range dependence and characterized by the fact that its autocorrelation function exhibits hyperbolic decay rather than exponential decay found in stationary ARMA time series. The FGN and other alternatives are discussed in Hipel and McLeod (2005).
1 | acvfFGN(H, maxlag)
|
H |
Hurst parameter |
maxlag |
acvf computed at lags 0,1,...,maxlag |
value of the autocorrelation at lag(s) k
The parameter H should be in (0,1). An error message is given if it is not.
