Does wind shape vegetation stripes? A copula-based mixture model for axial and circular data


Motivated by a case study of vegetation patterns, we introduce a mixture model with concomitant variables to examine the association between the orientation of vegetation stripes and wind direction. The proposal uses a novel copula-based bivariate distribution for mixed axial and circular observations. It provides a parsimonious and computationally tractable approach to examining the dependence of two environmental variables observed in a complex manifold.
