Computes a diffusion estimate of intensity for a point pattern.
densityHeat(x, sigma, ...)Depends on the class of x.
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.
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.
