摘要
本文研究伽玛密度函数的单调性及其极大值,研究了伽玛密度函数极大值函数与相应参数之间的关系.发现了伽玛分布的密度函数的极大值的变化规律.加深对伽玛分布的认识和理解,为伽玛分布的教学提供更多教学素材.
In this paper,the monotonicity and maximum of gamma density are studied.The relationship between the maximum function of gamma density and parameter was studied.The change law of the maximum of gamma distribution density was obtained.The understanding of gamma distribution is deepened.More teaching materials are provided for the teaching of gamma distribution.
