“…play an important role in some characterization problems of mathematical statistics. The class of probability distributions with density functions p α,ν,θ (x) have found some interesting properties and applications [2,4,5,7,8,9,24,29,30,32,33,34,35,36,37,38,41,43,44,45,51,52,60,61,64,65,66,68]. In particular, they are good candidates to model financial data which exhibits high kurtosis and heavy tails.…”
