24 Jan 2010: 1. Ask your supervisor to test you on the sheet of common distributions handed out inlectures.

24 Feb 2010: 9. Derive from first principles the form of the size α likelihood ratio test of equality ofmeans in the one-way ANOVA model of 4.

23 Feb 2010: In each case, explain how would you test these hypotheses, assuming that thefitted values in each cell are not too small.

29 Jan 2010: How would you perform the hypothesis test?[Hint: from the first example sheet rank(P ) = p, and rank(I P ) = n p.Similar arguments give that rank(P0) = p0.
