Some remarks on recent characterizations of continuous distributions

We would closely look at two recent published papers dealing with characterizations of certain univariate continuous distributions. we shall explain that the main results reported lack important assumptions. these results nevertheless are based on the conditional expectations of monotone functions of the generalized order statistics. we will also mention that similar results have recently been reported without the assumption of monotonicity of the functions of the generalized order statistics. © 2014 pakistan journal of statistics.
