Multivariate Procedures Invariant Under Linear Transformations
Many well-known procedures in multivariate data analysis are invariant under the group, L(p), of translations and nonsingular linear transformations. New maximal L(p) invariant statistics are derived and are shown to have the geometrical interpretation of a scatter of points in Euclidean space. The...

Summary: | Many well-known procedures in multivariate data analysis are invariant under the group, L(p), of translations and nonsingular linear transformations. New maximal L(p) invariant statistics are derived and are shown to have the geometrical interpretation of a scatter of points in Euclidean space. The distribution of maximal L(p) invariants for the case of a single multivariate normal population is shown to follow from a result of James (1954). Finally we consider tests of the null hypothesis that$k > 1$populations are identical and show that optimal L(p) invariant tests are similar tests of randomness. |
