+ 贝叶斯派的人认为,被估计的参数同样服从一种分布,即参数也为一个随机变量。他们在估计参数前会先带来先验知识,例如参数在 [0.5,0.6] 的区域内出现的概率最大,在引入了先验知识后在数据量小的情况下估计出来的结果往往会更合理。 + 贝叶斯派认为参数是一个随机变量,对它做估计就是计算其后验概率分布$P(\thet...
They generally use floats, which might be a loss of precision, but for small integers that should mean no problem at all. All of those methods that use floats have the same (or nearly the same) limit from this. If you still want to use this method and get float results, it should ...
