Dear John,
Thanks for your reply. when I saw your example, I learned why I did wrong
(In my experiment the individuals in different plots (in different stand density)
suffer from different competition intensity. I hope to analyse the relationship
between competition index and trees response to drought while exclude the
impact of difference among plots characteristic. So I set the ID of plot as
random effect and translate it to factors not competition index. Thus I did
wrong. And when I used the dataset of sleepstudy making an example, I also
did the same error.). Thank you very much.
Best regards,
Rumeng He
