difference or did I obviously miss something? Thank you!

Hi, All,
My data collection is from 4 regions (a, b, c, d). Within each region, it has 2

covariates. Both y and covariates were measured at
Thank you very much David. I should realize myslef that operator precedence

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 i
