vonMises
Package for dealing with the von Mises periodogram
...The von Mises periodogram is a data-analysis period-search tool that models the periodic signal with the so-called von Mises function, K exp(nu cos x).
The package can be used to compute the periodogram itself, as well as its detection significance levels. It can also perform some Monte Carlo simulations of the periodogram.
The details of the theory are given in the following refereed paper:
Baluev R.V., 2013, MNRAS, V. 431, P.1167-1179.
The version 1.0 uploaded here is the same package as the one that can be downloaded along with the above paper as "Supporting information". ...
