[R] extremely large negative AIC value in lme mode fitting
Hi, Everyone, I am trying to fit a ring specific gravity dataset using the linear mixed-effects model (lme function) in R. However, the AIC value is extrememly low (such as -8000) and the loglikehihhod value is extremely big (such as 4000), which seems not correct to me. What could the result indicate? Thank you very much. Yuzhen [[alternative HTML version deleted]]
