Coutsourides (1980) derives a. a. hoc nuisa.ce pa.a.eter remova. test for testing the equa.ity of two multiple correla.ion coefficients of two independent p va.ia.e norma. popula.ions, under the a.sumption tha. a.sa.ple of size n is a.a.la.le from ea.h popula.ion. He a.so extends his a. hoc nuisa.ce pa.a.eter remova. test to the testing of the equa.ity of two multiple correla.ion ma.rices. This pa.er presents lik.lihood ra.io tests for testing the equa.ity of k.multiple correla.ion coefficients, a.d a.so k.pa.tia. correla.ion coefficients.
