I comment here on a recent paper in this journal, on the fitting of truncated normal distributions by the EM algorithm. I show that the fitting of such distributions by direct numerical maximization of likelihood (rather than EM) is straightforward, contrary to an assertion made by the authors of that paper.
我在这里评论该杂志上的一篇关于通过 EM 算法拟合截断正态分布的最新论文。我表明，直接通过最大似然数值优化（而不是 EM）拟合此类分布非常简单，这与该论文作者的断言相反。
