WebClearly, expectiles depend only on the distribution of the random variable X; they can be seen as statistical functionals defined on the set of distribution functions with finite mean on ℝ. Quantiles and expectiles are closely connected as measures of non-central location. WebThe variable household income of the participants is coded in three categories, while the educational level is coded in five categories. Sex is a binary variable. ...
