Triplet Interaction Family

An object describing the family of all Gibbs point processes with interaction order equal to 3.

models, spatial

Advanced Use Only! This structure would not normally be touched by the user. It describes the interaction structure of Gibbs point processes which have infinite order of interaction, such as the triplet interaction process Triplets. Anyway, is an object of class "isf" containing a function$eval for evaluating the sufficient statistics of a Gibbs point process model taking an exponential family form.
