On parameter estimation and goodness-of-fit testing for spatial point patterns

The paper discusses the objectives of spatial point pattern analsis with particular reference to the distinction between mapped and sampled data. For the former case available nlodels are reviewed briefly the role of preliminary testing is discussed and a procedure for ftting a parametric sslodel is outlined. A simulation studA of several tests of spatial randonlness is intended to provide some insight into the suitability for model-fitting of various summasy descriptions of a mapped pattern. Two examples illustrate the use of the statistical techniques. Soss1e problem areas which-merit further investigation are identified.
