赤池信息量准则（AIC）有什么合理的解释吗？ 如何能推导出其中神奇的系数2？ AIC=2k-2ln (L)，此处k为自由度，L为似然函数。 这里的系数2从何而来，尤其是自由度前的那一个。

由此可知 AIC 准则的重要优点: AIC 准则在合理控制了自由参数的同时，也使得似然函数尽可能 大，模型的拟合度尽可能高。 2.2 BIC 准则简介 Bayesian Information Criterion (BIC) 也被称贝叶斯信息准 …

Jun 3, 2009 · Be nice..newby here.. I am working on a project with 600amp at the main. the main feeds 3 panels, each with 200amps. my question is, how do you calculate the AIC rating of these 3 …

根据定义， AIC = 2 ln (log-likelihood) + 2 k ，其中 ln (log-likelihood) 为分布模型拟合得到的对数似然函数值， k 为模型参数的个数（你这里用的三个分布各有两个参数，即 k = 2 ），所以你只需要把你拟 …
