In this work we consider a power series of the form X=∑j=0∞δjZj where 0δ1 and {Zj}j≥0 is an i.i.d. sequence of random variables. We show that X is well-defined iff E[(log|Z0|)+]∞ and establish a number of properties of the distribution of X, such as continuity and closure under...

Motivated by the observation that for a sample of size two from an exponential distribution, the largest order statistic is distributed as a convolution of two independent exponential random variables with distributions differing only in their intensity or rate parameter, a spectrum of related...
