Re: [R] Degree of freedom in the linear mixed effect model using lme function in R

Hi Sidzabda, Adjusting df for non-sphericity is generally not discussed in modern mixed effects modeling because likelihood-based estimators are far more flexible in structuring covariance matrices than the classical method of moments estimators based on expected mean squares. However, there are

[R] Degree of freedom in the linear mixed effect model using lme function in R

Hello, I would appreciate if somebody could help me clear my mind about the below issues. I have a factorial experiment to study the effects of Grazing and Fire on Forest biomass production. The experimental unit (to which the treatment combinations are applied) are PLOTs. The measures were made
