## S3 method for class 'slrm':
logLik(object, ..., adjust = TRUE)"slrm".logLik for fitted spatial logistic
regression models (objects of class "slrm", usually obtained
from the function slrm). It computes the log-likelihood
of a fitted spatial logistic regression model. If adjust=FALSE, the loglikelihood is computed
using the standard formula for the loglikelihood of a
logistic regression model for a finite set of (pixel) observations.
If adjust=TRUE then the loglikelihood is adjusted so that it
is approximately comparable with the likelihood of a point process
in continuous space, by subtracting the value
$n \log(a)$
where $n$ is the number of points in the original point pattern
dataset, and $a$ is the area of one pixel.
