Detecting multivariate outliers is mainly disregarded or done by using the basic Mahalanobis distance. However, that indicator uses the multivariate sample mean and covariance matrix that are particularly sensitive to outliers. Hence, this method is problematic. We highlight the disadvantages of the ...
马氏距离(Mahalanobis distance)是由印度统计学家马哈拉诺比斯(P. C. Mahalanobis)提出的，表示点与一个分布之间的距离。它是一种有效的计算两个未知样本集的相似度的方法。与欧氏距离不同的是，它考虑到各种特性之间的联系（例如：一条关于身高的信息会带来一条关于体重的信息，因为两者是有关联的），并且是尺度无...
