%0 Journal Article %T A unified approach for mixtures from two certain families of distributions %A A. A. A. Rahman %J Applied Mathematical Sciences %D 2013 %I %X A mixture from two distribution families is characterized via a differential equation as well as a recurrence relation between three consecutive conditional moments of some function h^k (X), k = 1, 2, 3 ... given X > y. Some wellknown results follow as special cases from our results. %K Characterization %K Mixture of Distributions %K Burr %K Pareto %K beta %K Weibull %K Exponential and 1st type Pearsonian Distributions %U http://www.m-hikari.com/ams/ams-2013/ams-29-32-2013/rahmanAMS29-32-2013.pdf
