autointensity {event}

Plot Autointensity Function of a Point Process

Description

autointensity plots the autointensity function of a point process, including a solid horizontal line indicating the constant intensity of a Poisson process.

Usage

autointensity(times, window=NULL, maxlag=max(times),
	ylab="Conditional probability", xlab="Lag",
	main="Autointensity function", xlim=c(0,max(times)),
	ylim=c(0,if(plotse)max(se1)else max(z$density)),
	lty=1, plot=TRUE, plotse=TRUE, add=FALSE, ...)

Arguments

times

Vector of times between events.

window

Width of grouping interval.

maxlag

Maximum lag to be calculated, by default the maximum interevent time.

plot

If FALSE, values are returned but the function is not plotted.

plotse

If TRUE, plots pointwise two-standard error bands around the curve.

add

If TRUE, add curve to an existing plot.

ylab

Plotting control options.

xlab

Plotting control options.

main

Plotting control options.

xlim

Plotting control options.

ylim

Plotting control options.

lty

Plotting control options.

...

Plotting control options.

Value

A list containing the coordinates of the plotted function and the standard error bands.
