WebJul 1, 2010 · The Fisher scoring method is widely used for likelihood maximization, but its application can be difficult in situations where the expected information matrix is not available in closed form or when parameters have constraints. In this paper, we describe an interpolation family that generalizes the Fisher scoring method and propose a general ... Web于是得到了Fisher Information的第一条数学意义：就是用来估计MLE的方程的方差。它的直观表述就是，随着收集的数据越来越多，这个方差由于是一个Independent sum的形式，也就变的越来越大，也就象征着得到的信息越来越多。
