Re : using predict() or fitted() from a model with offset; unsolved, included reproducible code
...fset(), completely ignoring the explanatory variable and that it is supposed to offset the effect in the first place:
such as, i get the same predicted values for?the 2 very different?models below. The summary table and coefficents?remain?perfectly valid though (and very different).
?
lmAO<-glm(MassChange24h~T1+offset(-2*AGE),? family=gaussian,na.action=na.exclude)
lmAO<-glm(MassChange24h~AGE,? family=gaussian,na.action=na.exclude)
Has anyone got any experience in predicting from models that include an offset term? Am I not specifying the offset term correctly in the model? Please get back to me...
