Quantile-Based Entropy function in past lifetime for Order Statistics and its properties

Zohreh Zamani, Mohsen Madadi

Abstract


In this paper, we introduce a quantile version of past entropy for order statistics and  study its properties.
 It is shown that this measure uniquely determine the quantile function.
 Also, we define two nonparametric classes of distribution based the proposed measure.  The closure of these classes under increasing convex (concave) transformations and weighted variables are discussed. Moreover, a new stochastic order based this measure is defined and some features of it are investigated.
   We give desirable conditions for a function of a random variable
 to have more   quantile past entropy for order statistics  
 than  original random variable.
