Title: A new Fourier series based construction for circulas Authors:  Arthur Pewsey - University of Extremadura (Spain) [presenting]
Abstract: A new Fourier series based construction is proposed for the analogues of copulas for circular distributions recently coined `circulas'. Different patterns of real Fourier coefficients are used to generate eight different classes of models, one of which is well-known within the literature. Approaches to model identification, fitting and goodness-of-fit testing are illustrated in the analysis of bird migration data.
