基于分组数据的指数分布的参数矩估计

Estimating Parameter in Exponential Distribution from Grouped Data

主要对分组数据的指数分布的参数进行估计,把分组数据的观察值看成多项分布的样本,利用矩估计的思想可得到参数的估计。当矩估计方程没有显式解时,Newton-Raphson迭代方法可以得到矩估计方程的解。

We consider the parameter estimation of exponential distribution in the context of survival analysis in the presence of grouped data.In order to acquire the estimating parameter,we deal with the observations of grouped data as the samples from diverse distribution and apply the moment estimating method.When the estimating equation has no explicit solution,the Newton-Raphson method is introduced.
