\title{Ord Interaction Process Family}
\description{
An object describing the family of all Ord interaction point processes
}
\details{
\bold{Advanced Use Only!}
This structure would not normally be touched by
the user. It describes
the family of point process models introduced by Ord (1977).
If you need to create a specific Ord-type model for use in
analysis, use the function \code{\link{OrdThresh}} or
\code{\link{Ord}}.
Anyway, \code{ord.family} is an object of class \code{"isf"}
containing a function \code{ord.family$eval} for
evaluating the sufficient statistics of any Ord type
point process model taking an exponential family form.
