摘要
本文提出了一个连续型随机变量的概率分布:指数差分布。讨论了该分布的极值、拐点、数学期望和方差,推导了参数的矩估计公式,探讨了该分布与指数分布的关系,给出了该分布在药代动力学中的应用。
A continuous probability distribution named as exponential difference distribution is presented in this paper,extreme value, inflection point, mathematical expectation and variance are dioscussed for this distribution, momtne estimation method is used to estimate parameters in this distribution, relationship between this distribution and geometric distribution is researched,and application of this distribution in pharmacokinetics is given.
