A series of cluster randomized trials CRTs carried out two decades ago in endemic areas in Africa demonstrated strong evidence that insecticide-treated bed nets ITNs can reduce child mortality. In addition to the direct effect, there was evidence for positive spillovers, or spatial indirect effects. From a recent systematic review, this example of positive spillover was found to be the first evidence of a spatial indirect effect of the bed net intervention, in addition to the direct effect that ITNs had in reducing mortality for those using them.

Spatial processes and statistics thereof
Breakthroughs in Statistics pp Cite as. Julian Besag has made a career of identifying emerging areas of statistics and writing important papers about them, just as they were beginning to attract serious attention. Thus Besag was the second major paper [after Geman and Geman , featured elsewhere in this volume] on the Markov random fields approach to image analysis, while in the s he made a number of contributions to Markov chain Monte Carlo MCMC sampling [e. His first major paper, however, laid out the foundations for statistical inference in lattice systems, and so provided the background for much later work, both his own and that of many others.

Authors: Panudet Saengseedam , Nanthachai Kantanantha. This paper proposes a linear mixed model LMM with spatial effects to forecast rice and cassava yields in Thailand at the same time. A multivariate conditional autoregressive MCAR model is assumed to present the spatial effects. The model is applied to the rice and cassava yields monthly data which have been extracted from the Office of Agricultural Economics, Ministry of Agriculture and Cooperatives of Thailand. The results show that the proposed model has better performance in most provinces in both fitting part and validation part compared to the simple exponential smoothing and conditional auto regressive models CAR from our previous study. Keywords: Bayesian Method , linear mixed model , multivariate conditional autoregressive model , spatial time series. Commenced in January
Characterising road networks has been the focus of a large body of research due to it being the main driver of activities in an urban ecosystem and the structuring factor in the dynamics of the city. One of these activities, and one with the largest economical impact in a city, is retail dynamics and its evolution. Therefore, the mathematical modeling of the location of retail activities and of the emergence of clustering in retail centers has as well generated a large number of works. Despite these two interwoven components strongly depending on one another and their fundamental importance in understanding cities, little work has been done in order to compare their local and global properties.

Nonparametric methods have been very popular in the last couple of decades in time series and regression, but no such development has taken place for spatial models. A rather obvious reason for this is the curse of dimensionality. For spatial data on a grid evaluating the conditional mean given its closest neighbors requires a four dimensional nonparametric regression. In this paper, a semi-parametric spatial regression approach is proposed to avoid this problem.
Julian Ernst Besag FRS 26 March — 6 August was a British statistician known chiefly for his work in spatial statistics including its applications to epidemiology , image analysis and agricultural science , and Bayesian inference including Markov chain Monte Carlo algorithms. Besag was born in Loughborough and was educated at Loughborough Grammar School. He began studying engineering at the University of Cambridge but moved to the University of Birmingham to study statistics, obtaining his BSc in He then spent a year as a research assistant to Maurice Bartlett at the University of Oxford before obtaining a lectureship at the University of Liverpool. He moved to the University of Durham in , where he became a professor in He was a visiting professor at the University of Washington in Seattle during —90 and, after a year at Newcastle University , returned to Seattle long-term. He officially retired in but remained an emeritus professor.
Why is there some kind of Catholic edict or something in the background? Image credit Jordan McDowall. Statistics on fields with index sets of more than one dimension of support and, frequently, an implicit 2-norm. Sometimes they are also time-indexed. Especially, for processes on a continuous index set with continuous state and undirected interaction. Sometimes over fancy manifolds , although often you can get away with plain old euclidean space, unless you if you are doing spatial statistics over the entire planet, which turns out to be curved. For spatial point processes I will make a new notebook.
Губы Стратмора приоткрылись, произнеся последнее в его жизни слово: Сьюзан. Воздух, ворвавшийся в ТРАНСТЕКСТ, воспламенился. В ослепительной вспышке света коммандер Тревор Стратмор из человека превратился сначала в едва различимый силуэт, а затем в легенду.
- Мне действительно нужно… На этот раз ее слова прервал резкий звонок мобильного телефона Стратмора. Коммандер поднес его к уху. - В чем дело? - рявкнул он и замолчал, внимательно слушая собеседника. Сьюзан на какое-то время забыла про Хейла. Она молила Бога, чтобы Стратмору звонил Дэвид.
