Circular Expectiles
Bernhard Klar
In this work, we introduce circular expectiles as minimizers of an asymmetric circular loss function based on chord distance. In contrast to the linear expectile criterion, the res…

On the application of Jammalamadaka-Jiménez Gamero-Meintanis test for circular regression model assessment
Katarina Halaj, Bernhard Klar, Bojana MiloÅ¡eviÄ +1
We study a circular-circular multiplicative regression model, characterized by an angular error distribution assumed to be wrapped Cauchy. We propose a specification procedure for…
