Distance estimates for dependent thinnings of point processes with densities

چکیده
In [Schuhmacher, Electron. J. Probab. 10 (2005), 165–201] estimates of the Barbour-Brown distance d2 between the distribution of a thinned point process and the distribution of a Poisson process were derived by combining discretization with a result based on Stein’s method. In the present article we concentrate on point processes that have a density with respect to a Poisson process, for which we can apply a corresponding result directly without the detour of discretization. This enables us to obtain better and more natural bounds in the d2-metric, and for the first time also bounds in the stronger total variation metric. We give applications for thinning by covering with an independent Boolean model and “Matérn type I”-thinning of fairly general point processes. These applications give new insight into the respective models, and either generalize or improve earlier results.

Distance estimates for Poisson process approximations of dependent thinnings
It is well known, that under certain conditions, gradual thinning of a point process on R+, accompanied by a contraction of space to compensate for the thinning, leads in the weak limit to a Cox process. In this article, we apply discretization and a result based on Stein’s method to give estimates of the Barbour-Brown distance d2 between the distribution of a thinned point process and an appro...
متن کاملA Heuristic Approach to Modelling Thinnings
Thinnings play an important role in guiding forest development and are considered by many to be the most important influence on forests in Central Europe. Due to their importance, thinning models are a major part of any forest growth model for managed forests. Existing thinning model approaches have a number of problems associated with structure and model development that weaken their reliabili...

متن کاملA new attitude coupled with the basic fuzzy thinking to distance between two fuzzy numbers
Fuzzy measures are suitable in analyzing human subjective evaluation processes. Several different strategies have been proposed for distance of fuzzy numbers. The distances introduced for fuzzy numbers can be categorized in two groups:\1. The crisp distances which explain crisp values for the distance between two fuzzy numbers.\2. The fuzzy distance which introduce a fuzzy distance for normal f...

Effect of time dependent normal transpiration on the problem of unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite circular cylinder moving simultaneously with time-depended angular and axial velocities and with time-dependent wall temperature or wall heat flux are investigated. The impinging free stream is steady with a strain rate . A re...
