Mahdi PY - 2020 DA - 2020/05/01 TI - Distributions of the Ratio and Product of Two Independent Weibull and Lindley Random Variables SP - 5693129 VL - 2020 AB - In this paper, we derive the cumulative distribution functions (CDF) and probability density functions (PDF) of the ratio and product of two independent Weibull and Lindley random variables. The moment generating functions (MGF) and the ķ-moment从比率和产物的情况下驱动。在这些推导，我们用一些特殊的功能，例如，广义超几何函数，超几何函数和抛物柱面功能。最后，我们得出的PDF和CDF在参数的许多值。SN - 1687-952X UR - https://doi.org/10.1155/2020/5693129 DO - 10.1155 /五百六十九万三千一百二十九分之二千○二十零JF - Hindawi出版KW - - ER概率统计PB的杂志 -
