There'll be zoom teaching Wed 15.4 and Mon 20.4 from 13:00, but not very long sessions. Check also Hjelpetr?d 3, and use it actively. Main themes now are

-- consolidation of likelihood things;

-- confidence curves;

-- basics of empirical processes.

-- Extra 1: let x be binomial (n,\theta), with n = 50 and x = 18. First do simple classical things for estimating \theta, with a 90 % c.i. Then make *two* confidence curves for \theta, and draw them in the same diagram: the simple normal approximation; and the one using the deviance function, ccval = pchisq(devval, 1), where you compute the deviance D(\theta) first. Check with Exercise 86.

-- Extra 2: suppose y_1, ..., y_n come from the Cauchy with unknown centre parameter \theta, i.e. with density

f = (1/\pi) / ( 1 + (y-\theta)^2 ).

Note that the mean is infinite, so the \bar y is hopeless. But there is a ML. Find...
