An object describing the Saturated Pairwise Interaction family of point process models
Advanced Use Only!
This structure would not normally be touched by the user. It describes the ``saturated pairwise interaction'' family of point process models.
If you need to create a specific interaction model for use in
spatial pattern analysis, use the function Saturated()
or the one existing implementation of a model in this family,
Geyer()
.
Geyer (1999) introduced the ``saturation process'', a modification of the
Strauss process in which the total contribution
to the potential from each point (from its pairwise interaction with all
other points) is trimmed to a maximum value c.
This model is implemented in the function Geyer()
.
The present class pairsat.family
is the
extension of this saturation idea to all pairwise interactions.
Note that the resulting models are no longer pairwise interaction
processes - they have interactions of infinite order.
pairsat.family
is an object of class "isf"
containing a function pairwise$eval
for
evaluating the sufficient statistics of any saturated pairwise interaction
point process model in which the original pair potentials
take an exponential family form.
