Locally Scaled K-function in Three Dimensions

Description

Estimates the locally-rescaled K-function of a 3D point pattern

Usage

K3scaled(
  X,
  lambda = NULL,
  ...,
  rmax = NULL,
  nrval = 128,
  correction = "none",
  renormalise = FALSE,
  normpower = 1
)

Arguments

X

A pp3

lambda

An estimate of the intensity function f(x,y,z). Defaults to a uniform intensity, estimated with intensity; this results in the same behavior as K3est.

correction

The correction to be used. Currently only the uncorrected estimate (correction = "none") is implemented.

In 3D the cube root is used instead of the square root to estimate the correction of the scaled intensity. Thas is, the eucledian distance between two points u[i] and u[j], d[ij], is multiplied by the mean of the cube roots of the local intensities lambda[c](u[i]) and lambda[c](u[j]).
