8.37. (Sec. 8.8) Let x~,), a = 1, ... , N., be observations from N(IL(·), I), v = 1, ... , q.

What criterion may be used to test the hypothesis that m

IL(·) = L 'Y"Ch. + IL, h~1 where Ch. arc given numbers and 'Y., IL arc unknown vectors? [Note: This hypothesis (that the means lie on an m-dimensional hyperplane with ratios of distances known) can be put in the form of the general linear hypothesis.]
