Determinantal Point ProcessesGrönblad Vesterinen, Marve, Enbom, Viktor January 2022 (has links)
We present and prove some important theorems regarding determinantal point processes. In particular we focus on existance and uniqueness theorems. Furthermore, we present an algorithm for generating determinantal point processes with a finite-dimensional projection kernel. Also, we go through the mathematical preliminaries required to understand the theory.

Densities and dependence for point processesFranzosa, Marie M. 28 January 1988 (has links)
Product densities have been widely used in the literature to give a
concrete description of the distribution of a point process. A rigorous
description of properties of product densities is presented with examples to
show that in some sense these results are the best possible. Product
densities are then used to discuss positive dependence properties of point
processes.
There are many ways of describing positive dependence. Two well
known notions for Bernoulli random variables are the strong FKG inequalities
and association, the strong FKG inequalities being much stronger. It is
known, for example, from van den Berg and Burton, that the strong FKG
inequalities are equivalent to all conditional distributions being associated,
which is equivalent to all conditional distributions being positively
correlated. In the case of point processes for which product densities exist,
analogs of such positive dependence properties are given. Examples are
presented to show that unlike the Bernoulli case none of these conditions are
equivalent, although some are shown to be implied by others. / Graduation date: 1988

General tightness conditions and weak convergence of point processesSchiopu-Kratina, I. (Ioana) January 1985 (has links)
In this dissertation, we consider two aspects of the theory of weak convergence of cadlag processes. / We first give a necessary and sufficient condition for the tightness of a sequence of cadlag processes (chapters 2,3) which generalizes Rebolledo's condition (see 13 ). It is a stochastic condition in the sense that stopping times rather than deterministic times are used in the statement. / We then discuss the predictability of the limit of a sequence of predictable processes (chapters 4-6). For a convergent sequence of point processes we show that, if the sequence of compensators converges, then the limit of compensators is the compensator of the limit of point processes (chapters 4,5). / Finally, we prove in Chapter 6 that extended weak convergence of a sequence of increasing predictable processes ensures the predictability of the limit.

SPATIAL POINT PROCESS ANALYSIS OF AT SEA SEAL ENCOUNTERSCarson, Stuart 09 December 2011 (has links)
We consider a data set comprising encounters between gray seals off Sable
Island in the autumn of 2009. We apply Spatial Point Pattern data analysis
approaches to this data set and demonstrate the effectiveness of these
techniques. Specifically we propose using point processes for clustered
data; the Inhomogeneous Poisson process, and the subset of cluster
processes called Cox processes. We utilize maximum likelihood methods to
produce a model for the mean intensity of the seal encounters which
includes spatial covariates. We then consider the impact of inhomogeneity
and review minimum contrast methods for fitting the Cox process models,
specifically the Thomas and Matern cluster processes. We demonstrate that
these methods allow us to gain valuable insight into the nature and extent
of grey seal encounters at sea. Finally we validate both our conclusions
and the approach taken using the most recent data available, that of
autumn 2010.
