Abstract
Let \({{X_{*}^{(r)}}}\) , r ≥ 1, denote generalized order statistics, with arbitrary parameters \({\gamma_{1},\dots,\gamma_{r}}\) , based on distribution function F. In this paper we characterize continuous distributions F by the regression of adjacent generalized order statistics, i.e. \({E\big( \psi\big(X_{*}^{(r)}\big) | X_{*}^{(r+1)} \big)=g\big(X_{*}^{(r+1)}\big)}\) where \({\psi,g:\mathbb{R}\mapsto\mathbb{R}}\) are continuous and increasing functions and ψ is strictly increasing. Further we investigate in detail the case when ψ(x) = x and g is a linear function of the form g(x) = cx + d for some \({c,\,d\in\mathbb{R}}\).
