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