syntex about a nested mixed linear model
...model I want to seek is:
Y = Dye + Temp + Dye + Temp*Dye + Array(Temp) + Dye*Array(Temp).
For F tests of Dye and Dye*Temp, then denominator factor is
Dye*Array(Temp). For F test of Temp, then denominator factor is
Array(Temp).
I wrote this syntax to fit the above model by typing:
R2.0<-lme(dsnx.0 ~ temp+Dye+temp*Dye, random = list(
Dye*Array(Temp)=pdDiag(~-1+temp*Dye), Arra=pdDiag(~-1+temp) ) ).
But there is syntax error message.
To obtain one solution, I typed
>int.dye<-interaction(Dye,temp:Arra,drop=T)
which created another factor, int.dye for 'Dye*Array(Temp)', and I
t...
