TSdist (version 2.2)

corDistance: Dissimilarities based on Pearson's correlation

Description

Computes two different distance measure based on Pearson's correlation between a pair of numeric time series of the same length.

Usage

corDistance(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.COR for more information.

Value

• d
  The computed distance between the pair of series.

Details

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