The package includes\nfunctions for estimating the variance- covariance matrix and\nfor testing single- and multiple- contrast hypotheses based on\nWald test statistics. Tests of single regression coefficients\nuse Satterthwaite or saddle-point corrections. Tests of\nmultiple- contrast hypotheses use an approximation to\nHotelling's T-squared distribution.
