摘要:Perfect sampling allows the exact simulation of random variables from the stationary measure of a Markov chain. By exploiting monotonicity properties of the slice sampler we show that a perfect version of the algorithm can be easily implemented, at least when the target distribution is bounded. Various extensions, including perfect product slice samplers, and examples of applications are discussed.

摘要:A warping is a function that deforms images by mapping between image domains. The choice of function is formulated statistically as maximum penalized likelihood, where the likelihood measures the similarity between images after warping and the penalty is a measure of distortion of a warping. The paper addresses two issues simultaneously, of how to choose the warping function and how to assess the alignment. A new, Fourier-von Mises image model is identified, with phase differences between Four...

摘要:In spatial statistics the data typically consist of measurements of some quantity at irregularly scattered locations; in other words, the data form a realization of a marked point process. In this paper, we formulate subsampling estimators of the moments of general statistics computed from marked point process data, and we establish their L-2-consistency. The variance estimator in particular can be used for the construction of confidence intervals for estimated parameters. A practical data-bas...

摘要:In recent years various sophisticated methods have been developed for the analysis of repeated measures. or longitudinal data. The more traditional approach, based on a normal likelihood function, has been shown to be unsatisfactory, in the sense of yielding asymptotically biased estimates when the covariance structure is misspecified. More recent methodology, based on generalized linear models and quasi-likelihood estimation, has gained widespread acceptance as 'generalized estimating equatio...

摘要:A common scenario in finite population inference is that it is possible to find a working superpopulation model which explains the main features of the population but which may not capture all the fine details. In addition, there are often outliers in the population which do not follow the assumed superpopulation model. In situations like these, it is still advantageous to make use of the working model to estimate finite population quantities, provided that we do it in a robust manner. The app...

摘要:Suppose that subjects in a population follow the model f (y*\x*; theta) where y* denotes a response, x* denotes a vector of covariates and theta is the parameter to be estimated. We consider response-biased sampling, in which a subject is observed with a probability which is a function of its response. Such response-biased sampling frequently occurs in econometrics, epidemiology and survey sampling. The semiparametric maximum likelihood estimate of theta is derived, along with its asymptotic n...

摘要:This paper considers fitting generalized linear models to binary data in non-standard settings such as case-control samples, studies with misclassified responses and misspecified models. We develop simple methods for fitting models to case-control data and show that a closure property holds for generalized linear models in the non-standard settings, i.e., if the responses follow a generalized linear model in the population of interest, then so will the observed response in the non-standard set...
