Assessing normality: mvnormtest provides a multivariate extension to the Shapiro-Wilks test, mvoutlier provides multivariate outlier detection based on robust methods. ICS provides tests for multi-normality. mvnorm.etest() in energy provides an assessment of normality based on E statistics (energy); in the same package k.sample() assesses a number of samples for equal distributions. mardia() in dprep provides the Mardia test for normality. Tests for Wishart-distributed covariance matrices are given by mauchly.test() in stats.

呵呵不知道有没有你要的。在贡献的包里找找
