Approximations for Von Mises
We prove Edgeworth expansions for degenerate von Mises statistics like the Beran, Watson, and Cram er-von Mises goodness-of-t statistics. Furthermore, we show that the bootstrap approximation works up to an error of order O(N ?1=2) and that Bootstrap based conndence regions attain a prescribed conndence level up to the order O(n ?1).
متن کاملCramér-von Mises regression
Consider a linear regression model with unknown regression parameters 0 and independent errors of unknown distribution. Block the observations into q groups whose independent variables have a common value and measure the homogeneity of the blocks of residuals by a Cramér-von Mises q-sample statistic Tq( ). This statistic is designed so that its expected value as a function of the chosen regress...
متن کاملVon Mises-Fisher Clustering Models
This paper proposes a suite of models for clustering high-dimensional data on a unit sphere based on von Mises-Fisher (vMF) distribution and for discovering more intuitive clusters than existing approaches. The proposed models include a) A Bayesian formulation of vMF mixture that enables information sharing among clusters, b) a Hierarchical vMF mixture that provides multiscale shrinkage and tre...
متن کاملThe Generalized Von Mises Distribution
A generalization of the von Mises distribution, which is broad enough to cover unimodality as well as multimodality, symmetry as well as asymmetry of circular data, has shown up in different contexts. We study this distribution in some detail here and discuss its many features, some inferential and computational aspects, and we provide some important results including characterization propertie...
متن کاملUnscented von Mises-Fisher Filtering
We introduce the Unscented von Mises–Fisher Filter (UvMFF), a nonlinear filtering algorithm for dynamic state estimation on the n-dimensional unit hypersphere. Estimation problems on the unit hypersphere occur in computer vision, for example when using omnidirectional cameras, as well as in signal processing. As approaches in literature are limited to very simple system and measurement models, ...
