##### Check Whether Point Process Model is Valid

Determines whether a point process model object corresponds to a valid point process.

Keywords
models, spatial
##### Usage
valid(object, …)
##### Arguments
object

Object of some class, describing a point process model.

##### Details

The function valid is generic, with methods for the classes "ppm" and "dppmodel".

An object representing a point process is called valid if all its parameter values are known (for example, no parameter takes the value NA or NaN) and the parameter values correspond to a well-defined point process (for example, the parameter values satisfy all the constraints that are imposed by mathematical theory.)

See the methods for further details.

##### Value

A logical value, or NA.
