SpecISDDistance {TSdist}

Dissimilarity Based on the Integrated Squared Difference between the Log-Spectra

Description

The dissimilarity of two numerical series of the same length is calculated based on the integrated squared difference between the non-parametric estimators of their log-spectra.

Usage

SpecISDDistance(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.ISD for more information.

Details

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

Value

d

The computed distance between the pair of series.
