How does MLE helps to find the variance components of linear models? I understood how MLE/REML provides best parameters for my data but how does it find variance components of linear models?

  • Could you explain what you mean by the "variance components of linear models"? The phrase is ambiguous. – whuber Jan 10 '22 at 23:24
  • yes by variance components i mean ...fixed and random effect of any linear models. – Ajay Jan 11 '22 at 08:15
  • How would those differ from the "best parameters"? – whuber Jan 11 '22 at 15:24
  • if i have a mixed model y=Xa+Zg+e...how does REML finds best estimates of my variances. lets say estimates of Zg which here is random factor. – Ajay Jan 12 '22 at 13:04
