pcfinhom.Track: Pair correlation funcrion of trajectory pattern

In trajectories: Classes and Methods for Trajectory Data

Pair correlation funcrion of trajectory pattern

Description

Pair correlation funcrion of trajectory pattern

Usage

pcfinhom.Track(X,timestamp,correction = c("translate", "Ripley"),q,
                sigma=c("default","bw.diggle","bw.ppl","bw.scott"),...)

Arguments

X	A list of Track objects
timestamp	based on secs,mins,...
correction	the type of correction to be used in computing pair correlation function
q	(optional) a numeric value between 0 and 1. quantile to be applied to calculate the variability area
sigma	method to be used in computing intensity function
...	passed to the arguments of pcfinhom

Details

This calculates the variability area of pair correlation function over time. If sigma=default, it calculates the variability area using the defaults of pcfinhom, otherwise it first estimate the intensity function using the given sigma as bandwidth selection method and then using the estimated intensity function, it estimates the variability area.

Value

an object of class "gTrack"
