Abstract
Plotting squared radii against their expected order statistics is used frequently as a graphical check of multivariate normality. The object of this article is to demonstrate that, by transforming the squared radii, an improved version of the standard χ2 probability plot can be obtained. At least empirically, the proposed method performs as well as that of Small (1978).Keywords
