| Abstract: | An objective method is developed for estimations of both spatial intensity of the point locations and spatial variation of a characteristic parameter of the distributions for the attached marks. Its utility is demonstrated by means of analyses of seismological and ecological data sets. |
| Keywords: | Marked point patterns intensity distributions of marks B-splines smoothing penalized likelihood objective Bayesian method magnitude frequency b-value |
