Dear all,


I conducted RCBD with subsampling ‘twice’ (Say, Feb and May).  Can I
consider two trials as random effect including blokc?  I used this formula
below.

fm.lme1 <- lme(response~trt, random= list(~1|block, ~1|trial), data=df)

Should I consider 'trt within block' as random too?

I would greatly appreciate any comment.

Thank you very much in advance,



Steve Hong
