Rr. Holden et M. Parent, NORMUL - A FORTRAN PROGRAM FOR TESTING MULTIVARIATE NORMALITY, Behavior research methods, instruments, & computers, 27(3), 1995, pp. 400-403
NORMUL is a FORTRAN program that provides a test of whether data confo
rm to a multivariate normal distribution. The method involves correlat
ing Mahalanobis distances for observed data with expected chi-square p
ercentile values. This obtained correlation is then tested for signifi
cance by empirically evaluating the probability of its belonging to a
distribution generated from multivariate normal data.
