Abstract A multivariate procedure for testing linear comparisons of vectors of adjusted group means of response (dependent) variables when groups differ in residual covariance and regression coefficient matrices is presented. Such disparities have been observed in investigations of trends in contaminant levels in fish. Application of the procedure is illustrated with data on Atlantic cod ( Gadus morhua ). The procedure is quite general and can be employed to test any linear comparisons.
