Multiple change-point detection on the circle via isolation using permutation testing
Sophia Loizidou, Andreas Anastasiou, Christophe Ley
In this paper we propose a new method for multiple change-point detection for piecewise-constant circular signals, a setting that, despite its importance in many scientific domains…
Modelling toroidal and cylindrical data via the trivariate wrapped Cauchy copula with non-uniform marginals
Sophia Loizidou, Christophe Ley, Shogo Kato +1
In this paper, we propose a new flexible family of distributions for data that consist of three angles, two angles and one linear component, or one angle and two linear components.…
Data-adaptive structural change-point detection via isolation
Andreas Anastasiou, Sophia Loizidou
In this paper, a new data-adaptive method, called DAIS (Data Adaptive ISolation), is introduced for the estimation of the number and the location of change-points in a given data s…
The trivariate wrapped Cauchy copula
Shogo Kato, Christophe Ley, Sophia Loizidou +1
In this paper, we propose a new flexible distribution for data on the three-dimensional torus which we call a trivariate wrapped Cauchy copula. Our trivariate copula has several at…
