TSdist (version 3.7.1)

ARPicDistance: Model-based Dissimilarity Measure Proposed by Piccolo (1990)

Description

Computes the model based dissimilarity proposed by Piccolo.

Usage

ARPicDistance(x, y, ...)

Value

d

The computed distance between the pair of series.

Arguments

x

Numeric vector containing the first time series.

y

Numeric vector containing the second time series.

...

Additional parameters for the function. See diss.AR.PIC for more information.

Author

Usue Mori, Alexander Mendiburu, Jose A. Lozano.

Details

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

Examples

# The objects example.series3 and example.series4 are two 
# numeric series of length 100 and 120 contained in the 
# TSdist package obtained from an ARIMA(3,0,2) process. 

data(example.series3)
data(example.series4)

# For information on their generation and shape see 
# help page of example.series.

help(example.series)

# Calculate the Piccolo distance between the two series using
# the default parameters. In this case an AR model is automatically 
# selected for each of the series:

ARPicDistance(example.series3, example.series4)

# Calculate the Piccolo distance between the two series
# imposing the order of the ARMA model of each series:

ARPicDistance(example.series3, example.series4, order.x=c(3,0,2), 
order.y=c(3,0,2))
