𝑇₃-Plot for Testing Spherical Symmetry for High-Dimensional Data with a Small Sample Size

Figure 2

𝑆𝑇₃-Plots for the two centerized subsets of data in Groups A and B from the VDP data on four selected projection directions. 𝑑₁, 𝑑₂, 𝑑₅, and 𝑑₆ have the same meaning as that for 𝐝₁,𝐝₂,𝐝₅, and 𝐝₆ as in Tables 1 and 2, respectively. For each plot, the region between the two dashdotted curves stands for the 99% acceptance region, the region between the two real-line curves for the 95% acceptance region, and the region between the two dashed curves for the 90% acceptance region.
