Envelope tests are a popular tool in spatial statistics, where they used goodness-of-fit testing. These graphically compare an empirical function $T(r)$ with its simulated counterparts from the null model. However, type I error probability $\alpha$ is conventionally controlled for fixed distance $r$ only, whereas functions inspected on interval of distances $I$. In this study, we propose two approaches related to Barnard's Monte Carlo test building global envelope $I$:(1) ordering and based...
Summary Pairwise interaction point processes form a useful class of models for spatial patterns, especially patterns which the distribution points is more regular than homogeneous planar Poisson process. Several authors have proposed methods estimating parameters pairwise However, there appears to be no general theory provides grounds preferring particular method, nor any extensive empirical comparisons been published. In this paper, we review three estimation in literature and present...
Abstract Model testing is a central step of spatial point pattern analysis, which allows ecologists to judge if their data agree with ecological hypotheses. We present simple and elegant solution challenging problem: the construction goodness‐of‐fit envelope test prescribed significance level α . Our new Analytical Global Envelope ( AGE ) not restricted narrow frame complete randomness its envelopes can be determined by mathematical calculations. This us investigate influence key settings on...
The article provides primary data on repeated tree measurements collected during two censuses a permanent sampling plot (440 m × 200 m) established in the old-growth polydominant broad-leaved forest Kaluzhskie Zaseki State Nature Reserve (centre of European Russia). time span between inventories was 30 years, and total 11 578 individuals ten tree, one shrub species, several undefined species three known genera were registered. During surveys, identity, stem diameter at breast height (DBH)...
Abstract The points of stationary and isotropic GIBBS point process are marked by exp(corresponding local energy). For the mean mark two product density functions very simple formulae true which contain intensity pair potential function process. Furthermore, there is a close connection between correlation covariance random field given conditional intensity.

Abstract In this paper we study relations between trunks and tops of pines in natural Siberian forests. By statistical methods show that the tend to deviate direction away from nearest neighbour tree or a summary trees given neighbourhood. an alternative approach into empty space near trunk position defined by corresponding Voronoi polygon.
