energy_fun

Description

Energy function

Usage

Energy_fun(
  f,
  f0,
  statistics,
  f_,
  f0_,
  statistics_,
  fn,
  p,
  p_,
  Lp,
  w_statistics
)

Arguments

f	Result of the calc_moments_full function which represents product-moment contribution of a point at coordinates x, y with marks, for the whole new ponit pattern.
f0	Column sums of the weights of the brand correlation functions of the new point pattern.
statistics	Results of the compute_statistics function for the new point pattern (calculation of optional spatial statistics).
fn	Determination of the weightings of the mark correlation functions.
p	Defines the initial state of the new ponit pattern.
p_	Reference point pattern.
Lp	Distance measure for the calculation of the energy function (Lp distance, 1 <= p <Inf).
w_statistics	Vector of named weights for optional spatial statistics from the spatstat package to be included in the energy calculation.This may include Dk, K, Hs, pcf.

Details

Defining the Energy_fun function to calculate the "energy" of the pattern (where a lower energy indicates a better match).
