Abstract

Semiparametric regression refers to the flexible incorporation of nonlinear functional relationships into regression analysis. Any application area that uses regression analysis may benefit from semiparametric regression. In this context, the main goal is to expand the censored regression models considering, on the one hand, that the response variable is linearly dependent on some variables, while its relationship with the other variables is characterized by non-parametric functions and, on the other hand, the random terms of the regression model belong to a class of symmetrical heavy tail distributions capable of accommodating extreme and/or influential observations in a better way than the normal distribution.
