spelling A test for directional-linear independence, with applications to wildfire orientation and sizedirectional datadirectional-linear densityindependence testnonparametric estimationpermutationswildfiresOriginal PaperA nonparametric test for assessing the independence between a directional random variable (circular or spherical, as particular cases) and a linear one is proposed in this paper. The statistic is based on the squared distance between nonparametric kernel density estimates and its calibration is done by a permutation approach. The size and power characteristics of various variants of the test are investigated and compared with those for classical correlation-based tests of independence in an extensive simulation study. Finally, the best-performing variant of the new test is applied in the analysis of the relation between the orientation and size of Portuguese wildfiresSpringerRepositório da Universidade de LisboaGarcía-Portugués, EduardoBarros, Ana M.G.Crujeiras, Rosa M.González-Manteiga, WenceslaoPereira, J.M.C.2014-07-25T15:51:11Z20142014-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/6996eng"Stochastic Environmental Research and Risk Assessment".
