Moments of Generalized Upper Record Values from Weibull- Power Function Distribution and Characterization

Tahir et al. (2014) proposed a new four parameter lifetime distribution called Weibull-power function distribution. In this article, some simple recurrence relations for the single and product moments as well as for inverse and quotient moments have been derived for the generalized upper record values ( k−th upper record values). Moreover, these relations are deduced for moments of upper record values. Furthermore, conditional expectation, recurrence relations for the single and product moments and truncated moment have been used to characterize this distribution
