  • Peakedness and peakedness ordering 

    El Barmi, Hammou; Mukerjee, Hari (Elsevier, 2012-05-10)
    The peakedness of a random variable (RV) X about a point a is defined by . A RV X is said to be less peaked about a than a RV Y about b, denoted by X≤pkd(a,b)Y, if P(|X−a|≤x)≤P(|Y−b|≤x) for all x≥0, i.e., |X−a| is ...
  • Peakedness and peakedness ordering in symmetric distributions 

    El Barmi, Hammou; Mukerjee, Hari (Elsevier Inc., 2009-04)
    There are many ways to measure the dispersion of a random variable. One such method uses the concept of peakedness. If the random variable X is symmetric about a point , then Birnbaum [Z.W. Birnbaum, On random variables ...
