ARMahDistance {TSdist}

Model-based Dissimilarity Proposed by Maharaj (1996, 2000)

Description

Computes the model based dissimilarity proposed by Maharaj.

Usage

ARMahDistance(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.AR.MAH for more information.

Details

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

Value

statistic

The statistic of the homogeneity test.

p-value

The p-value issued by the homogeneity test.

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 ar.mah distance between the two series using
# the default parameters. 

ARMahDistance(example.series3, example.series4)

# The p-value is almost 1, which indicates that the two series come from the same 
# ARMA process.
