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.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
