Arguments passed to |
This function fits a point process model to data that specify
a point pattern on a linear network. It is a counterpart of
the model-fitting function ppm
designed
to work with objects of class "lpp"
instead of "ppp"
.
The argument X
should be an object of class "lpp"
(created by the command lpp
) specifying a point pattern
on a linear network.
The subsequent arguments ...
will be passed to
ppm
. They specify the form of the model.
An object of class "lppm"
representing the fitted model.
There are methods for print
, predict
,
coef
and similar functions.
