Hi all, I would like to know how the BIC criterion is calculated for models estimated using gls( ) function. I read in Pinheiro & Bates (2000) p84 that BIC = -2logL + npar*log(N) (for the ML method), or BIC = -2logLR + npar*log(N-p) (for the REML method) but when I use any of these formulae I don't obtain the result given by R. Thanks in advance for any help. Eve CORDA Office national de la chasse et de la faune sauvage (http://www.oncfs.gouv.fr) BP 20 78612 Le Perray en Yvelines Cedex FRANCE Phone: +3...
