densityHeat: Diffusion Estimate of Point Pattern Intensity

In spatstat.explore: Exploratory Data Analysis for the 'spatstat' Family

Diffusion Estimate of Point Pattern Intensity

Description

Computes a diffusion estimate of intensity for a point pattern.

Usage

densityHeat(x, sigma, ...)

Arguments

x	Point pattern (object of class "ppp" or another class).
sigma	Smoothing bandwidth. Usually a single number giving the equivalent standard deviation of the smoother.
...	Additional arguments depending on the method.

Details

The generic function densityHeat computes an estimate of point process intensity using a diffusion kernel method.

Further details depend on the class of point pattern x. See the help file for the appropriate method.

Value

Depends on the class of x.

For two-dimensional point patterns (objects of class "ppp"), the diffusion kernel estimator is densityHeat.ppp. The usual kernel estimator is density.ppp, and the tessellation-based estimator is adaptive.density.
