is there a closed form of the CF (characteristic function) of a bivariate von Mises distribution?

is there a closed form of the CF (characteristic function) of a bivariate von Mises distribution? And if I have two parameters that follow von Mises distribution, but my two parameters will be mixed ...

Variance of Multimodal Generalized von Mises Distribution?

How do you calculate the variance of a Multimodal Generalized von Mises (MGvM) distribution? Given its complexity with multiple modes and asymmetry, I'm looking for: Any formula or method to calculate ...

Analytically estimate joint Von Mises distribution parameters from multiple underlying distributions with arbitrary weights

Given a set of n one dimensional (circular) Von Mises distributions, it is possible to randomly sample each distribution (with a different weight, ...

Maximum Entropy distribution of a ticking clock

Say I have a clock that emits "ticks". An ideal clock looks like a dirac comb. It has: perfect periodicity of ticks (there is a precise fixed time interval between any two consecutive ticks)...

What concentration $\kappa \in [0, \infty)$ maximizes the entropy of the von Mises-Fisher distribution?

I'd like to prove what concentration parameter $\kappa \in [0, \infty)$ maximizes the (differential) entropy of a von-Mises Fisher Distribution. The differential entropy of of a von Mises-Fisher ...

Calculating the parameters of von Mises distribution

I would like to calculate the values of the concentration ($\kappa$) and mean direction ($\mu$) for a von Mises mixture model from the theta values given by the movMF() function in R. At the bottom of ...

Alternative to Von Mises distribution?

I'm in the middle of a replication project in some previous studies using another stimulus space than these previous studies. I want to test whether the estimation was made based on one or the other ...

What transformations preserve the von Mises distribution?

The von Mises distribution is entirely defined on the circle with a density given by $$f(x) = (2\,\pi\, I_0(\kappa))^{-1} \exp(\kappa \cos(x-\mu))\ ,$$ where $x$ is in an arbitrary real interval of ...

Von Mises distribution to detect outliers

I am working out the difference between two angles from a circle, and I work out the mean difference across 96 trials in 10 separate samples. In order to detect outliers for statistical analysis, ...

Estimating kappa of von Mises distribution

Is there a way to calculate an estimate of the parameter $\kappa$ from data for the von Mises distribution? It seems very easy to do in R, http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=CircStats:A1inv,...
