A new oxo-azamacrocyclic ligand: 13,27-dimethyl-6,20-dioxa-3,9,17,23-tetraaza-tricyclo[23.3.1^(11,15)]triaconta-1 (29),11, 13,15(30),25,27-hexaene-29,30-diol, and a dinuclear copper(II) complex: syntheses, characterization and binding ability

In multivariate data with n individuals described by p variables it is usual to assume that the variables are fixed and the individuals are randomly selected; in the present study we assume that the individuals are fixed and the previously normalised variables are randomly selected from a population of variables. When we want to associate to the sample of variables a distribution, like the Bingham distribution, it is important to use beforehand a test of uniformity. In this article, we compare the power of Bingham and Gine tests of uniformity for some dimensions of the sphere, vs. a Bingham population or a mixture of Bingham populations.
