Hello everybody,

Please help with connecting the AIC and BIC numbers printed by summary.gls to the logLik number.


 1.  is the logLik number the true ML or density scaling constants have been omitted?
 2.  what is the formula for calculating the AIC and BIC from logLik (and how can I see it)? I tried printing summary.gls but it says object not found.

Thank you very much.
Stephen
