MindistSaxDistance {TSdist}

Symbolic Aggregate Aproximation based dissimilarity

Description

Calculates the dissimilarity between two numerical series based on the distance between their SAX representations.

Usage

MindistSaxDistance(x, y, w, ...)

Arguments

x

Numeric vector containing the first time series.

y

Numeric vector containing the second time series.

w

The amount of equal sized windows that the series will be reduced to.

...

Additional parameters for the function. See diss.MINDIST.SAX for more information.

Details

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

Value

d

The computed distance between the pair of series.

Examples

# The objects example.series3 and example.series4 are two 
# numeric series of length 100 and 120 respectively. 

data(example.series3)

help(example.series)

# Calculate the mindist.sax distance between the two series using
# 20 equal sized windows for each series. The rest of the parameters
# are left in their default mode.
