From moment explosion to the asymptotic behavior of the cumulative distribution for a random variable
S. M. Aly Uppsala University, Department of Mathematics
Abstract:
We study the Tauberian relations between the moment generating function (MGF) and the complementary cumulative distribution function of a random variable whose MGF is finite only on part of the real line. We relate the right tail behavior of the cumulative distribution function of such a random variable to the behavior of its MGF near the critical moment. We apply our results to an arbitrary superposition of a CIR process and the time-integral of this process.
Keywords:
regular variation, Tauberian theorems, moment generating function, tail asymptotic, CIR process.
