PredDistance {TSdist}

Dissimilarity Measure Based on Nonparametric Forecasts

Description

The dissimilarity of two numerical series of the same length is calculated based on the L1 distance between the kernel estimators of their forecast densities at a given time horizon.

Usage

PredDistance(x, y, h, ...)

Arguments

x

Numeric vector containing the first time series.

y

Numeric vector containing the second time series.

h

Integer value representing the prediction horizon.

...

Additional parameters for the function. See diss.PRED for more information.

Details

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

Value

d

The computed distance between the pair of series.
