What simple book is there for free, in which it is told how to calculate ‘studentized’ residuals? I am stuck [on page 71 of the freely downloadable pdf of] ‘Design and analysis of cross-over trials’ by Jones and Kenward. They give the figures for their model, but don’t quite explain how they obtained them.
On a related note, how does one calculate within-subject variance, given one baseline measurement? I am afraid that my subjects are small enough that I can’t obtain many totally different samples for the variable.
