pcfinhom.Track: 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"),...)

Value

an object of class "gTrack"

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.
