It is shown that comparison of linear models with singular covariance matrices may be reduced to the same problem for non-singular covariance matrices. Moreover, the problem of linearly sufficient statistics, considered by \textit{H. Drygas}, Sankhyā, Ser. A 45, 88-98 (1983; Zbl 0535.62007), is reduced to comparison of linear models.
