Check Whether Point Process Model is Valid
Determines whether a point process model object corresponds to a valid point process.
valid(object, ...)
object |
Object of some class, describing a point process model. |
... |
Additional arguments passed to methods. |
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.
A logical value, or NA.
