In TSdist: Distance Measures for Time Series Data

General Spectral Dissimilarity Measure Using Local-Linear Estima- tion of the Log-Spectra

Description

The dissimilarity of two numerical series of the same length is calculated based on the ratio between local linear estimations of the log-spectras.

Usage

SpecLLRDistance(x, y, ...)

Arguments

x	Numeric vector containing the first time series.
y	Numeric vector containing the second time series.
...	Additional parameters for the function. See diss.SPEC.LLR for more information.

Details

This is simply a wrapper for the diss.SPEC.LLR function of package TSclust. As such, all the functionalities of the diss.SPEC.LLR function are also available when using this function.

Value

d	The computed distance between the pair of series.
