Non-parametric methods for circular-circular and circular-linear

Carnicero, José Antonio; Wiper, Michael P.; Ausín, … - Departamento de Estadistica, Universidad Carlos III de … - 2011

We present a non-parametric approach for the estimation of the bivariate distribution of two circular variables and the modelling of the joint distribution of a circular and a linear variable. We combine nonparametric estimates of the marginal densities of the circular and linear components with...
