Abstract [eng] |
Let $\xi_{1}, \xi_{2}, \ldots, \xi_{n}$ be a sequence of independent identically distributed random variables and let $\Pi_{n}:=\prod_{k=1}^{n} \xi_{k}$ be the product of the variables. Also, we assume that all random variables are gamma-distributed. This paper considers the asymptotic behaviour for the probability $P(\Pi_n>x)$. We will prove 2 theorems for the asymptotic formula of product of distributions. All theorems are proved by the mathematical induction method. |
