valid {spatstat} | R Documentation

## Check Whether Point Process Model is Valid

### Description

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

### Usage

      valid(object, ...)

### Arguments

`object` | Object of some class, describing a point process model.
`...` | Additional arguments passed to methods.

### 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`.
