sdfPLA: Spectral density function for PLA
In FGN: Fractional Gaussian Noise and power law decay time series model fitting

Description Usage Arguments Details Value Author(s) See Also Examples

Computes the spectral density function for the PLA model with parameter a at the Fourier frequencies, 2*Pi*j/n, j=1,...,[n/2], where n is the length of the time series. The evaluation is very fast. Bivariate interpolation and asymptotic approximation are used.

1	sdfPLA(a, n)

`a`	PLA parameter
`n`	length of time series

The details of the implementation are discussed in the accompanying vignette. The parameter a should be in the interval (0,2). series n should be greater than 2.

a vector of length [n/2] of the spectral density values.
