Choose Parametric Tests or Their Nonparametric Counterparts

Test whether four-dimensional populations have equivalent location vectors, using a collection of parametric and nonparametric tests.

Wolfram Language code:

BlockRandom[SeedRandom[42];
	data1 = RandomVariate[MultinormalDistribution[{.25, .25, 0, .5}, IdentityMatrix[4]], 50];
	data2 = RandomVariate[MultinormalDistribution[{-.25, -.25, 0, .25}, IdentityMatrix[4]], 50]];

Wolfram Language code:

Labeled[BubbleChart3D[{data1, data2}, ChartStyle -> {Directive[{Specularity[White, 10], Orange}], Directive[{Specularity[White, 10], Purple}]}, PerformanceGoal -> "Quality", ImageSize -> 250], Insert[LocationTest[{data1, data2}, Automatic, {"TestDataTable", All}], ItemStyle -> Bold, {1, 2}], {Right, Bottom}]
