1 Estimation 1.1 EM algorithm We derive the EM algorithm for Uks withGamma( k; ) distributions, so S = Pp k=1 Uk isGamma( ; ) with = Pp k=1 k andW = U=S is Dirichlet( 1; : : : ; p), and S andW are independent. With a slight abuse of notation we are going to identify xB = ft1; : : : ; tmg with (m; t) from now on. The joint density of (m; t) and the latent variables (y; s;w) is f(m; t;y; s;w) = f...
متن کاملTESTING FOR AUTOCORRELATION IN UNEQUALLY REPLICATED FUNCTIONAL MEASUREMENT ERROR MODELS
In the ordinary linear models, regressing the residuals against lagged values has been suggested as an approach to test the hypothesis of zero autocorrelation among residuals. In this paper we extend these results to the both equally and unequally replicated functionally measurement error models. We consider the equally and unequally replicated cases separately, because in the first case the re...

متن کاملMixed models for the analysis of replicated spatial point patterns.
The statistical methodology for the analysis of replicated spatial point patterns in complex designs such as those including replications is fairly undeveloped. A mixed model is developed in conjunction with maximum pseudolikelihood and generalized linear mixed modeling by extending Baddeley and Turner's (2000, Australian and New Zealand Journal of Statistics 42, 283-322) work on pseudolikeliho...
متن کاملEstimation of summary characteristics from replicated spatial point processes
characteristics play an important role in the analysis of spatial point processes. We discuss various approaches to estimating summary characteristics from replicated observations of a stationary point process. The estimators are compared with respect to their integrated squared error. Simulations for three basic types of point processes help to indicate the best way of pooling the subwindow es...
