Statistical properties are given and an application to estimate the cost of traffic accidents in an innovative insurance data set that has information on driving style is presented. A new kernel approach for the estimator covariance matrix is provided. Both, the simulation study and the real case show that the method provides the best results when data are highly skewed and when the conditional distribution is of interest. Supplementary materials containing appendices are available online.46 p.application/pdfengcc-by-nc-nd, (c) Bolancé Losilla et al., 2018http://creativecommons.org/licenses/by-nc-nd/3.0/es/Avaluació del riscEstadística no paramètricaAssegurances d'accidentsRisk assessmentNonparametric statisticsAccident insuranceinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/openAccess
