  2. 1. On perfect simulation and EM estimation

    Author : Kajsa Larson; Sara Sjöstedt de Luna; Mats Rudemo; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfect simulation; coupling from the past; Markov chain Monte Carlo; point process; Widom-Rowlinson model; EM algorithm; dispersal distribution; fecundity; first-passage percolation; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : Perfect simulation  and the EM algorithm are the main topics in this thesis. In paper I, we present coupling from the past (CFTP) algorithms that generate perfectly distributed samples from the multi-type Widom--Rowlin-son (W--R) model and some generalizations of it. READ MORE

  4. 2. On Perfect Simulation of Markovian Queueing Networks with Blocking

    Author : Dan Mattsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Markov chain; Monte Carlo methods; Propp-Wilson algorithm; perfect simulation; queueing theory; Jackson networks; birth and death processes; Jackson networks;

    Abstract : Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent onoff processes. READ MORE

  5. 3. Perfect simulation of some spatial point processes

    Author : Kajsa Larson; Olle Häggström; Chalmers University of Technology and Göteborg University Department of Mathematical Statistics; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfect simulering; coupling from the past; Markov shain Monte Carlo; point process; Widom-Rowlinson model; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : Coupling from the past (CFTP) algorithms are presented that generate perfectly distributed samples from the multi-type Widom--Rowlinson (W--R) model and some generalizations of it. The classical W--R model is a point process in the plane or the  space consisting of points of several different types. READ MORE
