Moment Properties of Dual Generalized Order Statistics Based on Fre ́chet-Weibull Distribution

The dual generalized order statistics or sometimes called lower generalized order statistics is a combined structure of examining random variables in decreasing order. In this paper, some simple recurrence relations for single and product moments of dual generalized order statistics from Fre ́chet-Weibull distribution have been derived and its special cases are discussed. The characterization results are also presented based on the recurrence relations
