Markov Chain Monte Carlo Methods for Fitting Spatiotemporal Stochastic Models in Plant Epidemiology

Strategies for controlling plant epidemics are investigated by fitting continuous time spatiotemporal stochastic models to data consisting of maps of disease incidence observed at discrete times. Markov chain Monte Carlo methods are used for fitting two such models to data describing the spread of citrus tristeza virus (CTV) in an orchard. The approach overcomes some of the difficulties encountered when fitting stochastic models to infrequent observations of a continuous process. The results of the analysis cast doubt on the effectiveness of a strategy identified from a previous spatial analysis of the CTV data. Extensions of the approaches to more general models and other problems are also considered.     

银行风险传染随机模型研究

借鉴生物学中传染病模型,建立了银行风险传染的随机模型。描述了银行风险在银行系统中的传染过程,分析了受传染银行的数目变化规律以及银行风险传染率、银行间的关联度和银行风险治理率对银行风险传染的影响。分析结果表明：通过降低传染率、降低关联度或增加治理率都可以控制银行风险的传染,并且降低银行间的关联度比增加治理率对控制银行风险传染的效果更好。     

Stochastic Multigrade Population Models in Continuous Time

A continuous time stochastic model for the analysis of wastage in a hierarchically structured multigrade population system, with non-homogeneous Poisson input, is developed in this paper. Special cases of the model are discussed and the distribution of the grade sizes at any time is obtained through the use of straightforward probabilistic arguments.     

Optimal Prediction in Stochastic Regression Models with Application to the Analysis of Repeated Surveys

Several results relating to the optimal prediction of regression coefficients and random variables under a general linear model with stochastic coefficients are presented. These results are then applied to the analysis of repeated sample surveys over time. In particular, if the finite population can be modelled by a superpopulation model, a fully efficient method for the analysis of repeated surveys is proposed.
