The 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 کاملRegularized Multivariate von Mises Distribution
Regularization is necessary to avoid overfitting when the number of data samples is low compared to the number of parameters of the model. In this paper, we introduce a flexible L1 regularization for the multivariate von Mises distribution. We also propose a circular distance that can be used to estimate the Kullback-Leibler divergence between two circular distributions by means of sampling, an...
متن کاملChange-point problems for the von Mises distribution
A generalized likelihood ratio procedure and a Bayes procedure are considered for change-point problems for the mean direction of the von Mises distribution, both when the concentration parameter is known and when it is unknown. These tests are based on sample resultant lengths. Tables that list critical values of these test statistics are provided. These tests are shown to be valid even when t...
متن کاملFrobenius Norm Regularization for the Multivariate Von Mises Distribution
Penalizing the model complexity is necessary to avoid overfitting when the number of data samples is low with respect to the number of model parameters. In this paper, we introduce a penalization term that places an independent prior distribution for each parameter of the multivariate von Mises distribution. We also propose a circular distance that can be used to estimate the Kullback–Leibler d...
متن کاملA Bivariate Generalized von Mises Distribution with Applications to Circular Genomes
To test for independence in evolution of paired circular genomes, including bacteria and archaea, we propose a bivariate distribution (BGVM) with generalized von Mises distributions. BGVM can model paired angular data with asymmetric or/and multi-modal marginals, which remain unexplored in the area. Some distributional properties, for instance shape parameters Correspondences should be addresse...
