Log Likelihood for Poisson Point Process Model
Extracts the log likelihood of a fitted Poisson point process model.
Usage
## S3 method for class 'ppm':
logLik(object, ...)Arguments
- object
- Fitted point process model.
An object of class
"ppm". - ...
- Ignored.
Details
The maximised value of the log likelihood for the fitted model (as approximated by quadrature using the Berman-Turner approximation) is extracted.
If object is not a Poisson process, the maximised log
pseudolikelihood is returned, with a warning.
Value
- A numerical value.
