Abstract
The theory of spherical distributions is employed to develop a generalized F-test for
testing the mean of a subfamily of elliptically contoured distributions. The exact null distribution
of the generalized F-test is obtained. The power performance of the generalized F-test is illustrated
by choosing several distributions in the subfamily of elliptically contoured distributions. The Monte
Carlos study shows that the generalized F-test is not sensitive to the increase of sample dimension.
The generalized F-test is applicable to the case of any dimension with any sample size. An analysis
on a real dataset in financial models illustrates possible applications of the proposed tests.
Keywords
Elliptically contoured distribution; generalized F-test; high dimension; spherically
symmetric distribution.
