Sign Tests in Multidimension: Inference Based on the Geometry of the Data Cloud
多维符号检验:基于数据点云几何的推断
Multivariate sign tests attracted several statisticians in the past, and it is evident from recent nonparametric literature that they still continue to draw attention. One of the most important features of the univariate sign test is that it does not involve much technical assumptions or complicacy, and this makes it quite popular among statistics users. In this article we have come up with a new method for constructing multivariate sign tests that have reasonable…
