Fits a long memory trawl function to equidistant univariate time series data
1 | fit_LMtrawl(x, Delta = 1, GMMlag = 5, plotacf = FALSE, lags = 100)
|
x |
vector of equidistant time series data |
Delta |
interval length of the time grid used in the time series, the default is 1 |
GMMlag |
lag length used in the GMM estimation, the default is 5 |
plotacf |
binary variable specifying whether or not the empirical and fitted autocorrelation function should be plotted |
lags |
number of lags to be used in the plot of the autocorrelation function |
The trawl function is parametrised by the two parameters H> 1 and α > 0 as follows:
g(x) = (1-x/α)^{-H},\mbox{ for } x ≤ 0.
The Lebesgue measure of the corresponding trawl set is given by α/(1-H).
alpha: parameter in the long memory trawl
H: parameter in the long memory trawl
LM: The Lebesgue measure of the trawl set associated with the long memory trawl
