DiggleGatesPointProcess

DiggleGatesPointProcess[μ,ρ,d]

represents a Diggle–Gates point process with constant intensity μ and interaction radius ρ in .

Details

DiggleGatesPointProcess models point configurations where the points have a softcore decreasing repulsive pairwise interaction for points within radius ρ of each other and that are otherwise uniformly distributed.
The Diggle–Gates point process can be defined as a GibbsPointProcess in terms of its intensity μ and the pair potential or pair interaction , which are both parametrized by ρ as follows:
pair potential

pair interaction
A point configuration from a Diggle–Gates point process DiggleGatesPointProcess[μ,ρ,d] in an observation region reg has density function proportional to $mu^n product_(i!=j)h(TemplateBox[{{{p, _, i}, -, {p, _, j}}}, Norm])$ , with respect to PoissonPointProcess[1,d].
The Papangelou conditional density for adding a point to a point configuration is $mu product_ih(TemplateBox[{{{p, _, i}, -, q}}, Norm])$ .
DiggleGatesPointProcess allows μ and ρ to be any positive number, and d to be any positive integer.
DiggleGatesPointProcess is a special case of GibbsPointProcess.
DiggleGatesPointProcess simplifies to PoissonPointProcess when .
