Fit Point Process Model to Point Pattern on Linear Network

Fit a point process model to a point pattern dataset on a linear network

Keywords
models, spatial
Usage
lppm(X, ...)
Arguments
X
Object of class "lpp" specifying a point pattern on a linear network.
...
Arguments passed to ppm.
Details

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.

Value

  • An object of class "lppm" representing the fitted model. There are methods for print, predict, coef and similar functions.
