\title{Triplet Interaction Family}
\description{
An object describing the family of all Gibbs point processes
with interaction order equal to 3.
}
\details{
\bold{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 \cite{\link{Triplets}}.
Anyway, \code{triplet.family} is an object of class \code{"isf"}
containing a function \code{triplet.family$eval} for
evaluating the sufficient statistics of a Gibbs
point process model taking an exponential family form.
}
\seealso{
\code{\link{Triplets}} to create the triplet interaction process
structure.
Other families:
\code{\link{pairwise.family}},
\code{\link{pairsat.family}},
\code{\link{inforder.family}},
\code{\link{ord.family}}.
