[HTML][HTML] The joint projected normal and skew-normal: A distribution for poly-cylindrical data

G Mastrantonio - Journal of Multivariate Analysis, 2018 - Elsevier
This paper introduces a multivariate circular–linear (or poly-cylindrical) distribution obtained
by combining the projected and the skew-normal. We show the flexibility of our proposal, its …

Modeling the seasonality of extreme coastal water levels with mixtures of circular probability density functions
