TSdist (version 2.1)

perDistance: Periodogram based dissimilarity

Description

Calculates the dissimilarity between two numerical series of the same length based on the distance between their periodograms.

Usage

perDistance(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.PER for more information.

Value

• d
  The computed distance between the pair of series.

Details

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