Description

Estimates the average mutual information index (ami) of a given time series for a specified number of lags

Usage

mutual(series, partitions = 16, lag.max = 20, plot=TRUE)

Arguments

series time series
partitions number of bins
lag.max largest lag
plot logical. If 'TRUE' (the default) the ami is plotted

Details

Estimates the mutual information index for a specified number of lags. The joint probability distribution function is estimated with a simple bi-dimensional density histogram.

Value

An object of class "ami", which is a vector containing the estimated mutual information index for each lag between 0 and lag.max.
