of the Geyer model. Like the analysis in Section 12.5, this has automatically detected the transition
between clustered and regu la r textures. For further details see [ 33].
13.12 Theory: Gibbs processes∗
This section summarises essential theory for finite Gibbs point process models including their prob-
ability densities and conditional inte nsities, and model-fitting techniques. For mo re detail, ...
