Deviance explined in GAMM, library mgcv
...of deviance explained when fitting a gam model using the mgcv library is straightforward:
summary(object.gam) $dev.expl
or alternatively, using the deviance (deviance(object.gam)) of the null and the fitted models, and then using 1 minus the quotient of deviances.
However, when a gamm (generalizad aditive mixed model) is fitted, the deviance is not displayed, and only the logLik of the underlying lme model can be derived (logLik(objetct.gamm$lme)), which is not enough to derive the percentage deviance explained because the logLik for the saturated model is not available.
Any suggestions o...
