Dear Joaquin,

Yes. I think you have found a typo. The prior to equation 5.13 should read "It
is relatively easy to show that $Y_i$ is normally distributed ..."

Best regards,

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
