I have noticed that some of the Poisson log normal parameter numbers in the result browser are incorrect. Does this mean I should not trust the AIC weightings? If so how can I compare models with incorrect parameter numbers?
And you know they're wrong because...?
If you're sure that MARK is reporting the wrong number of parameters (which can happen as a function of the numerical optimization of the likelihood -- this is discussed at several points in the MARK book -- see addendum to Chapter 4, for example), then you simply manually adjust the parameter count to the 'correct' number of parameters. This is also discussed in several places in the MARK book.
On a separate note, please could you send me a link to Garry Whites Lectures on the Colorado State University website as the link from the Mark website is broken.
Thank you,
Sarah
The contents of those notes in largely contained in, and in many cases, superseded by the more detailed treatment in the MARK book (and there is a lot in the MARK book that isn't in Gary's notes, because he last taught the 'estimation class' before some models were available in MARK.)
