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
