Hi all,
I have the following data and would like to consider the following model:
value = type + batch (type) + beta1* month +beta2*type*month+ error
Here type is fixed effect and batch is a random effect neste within type,
and month is continuous.
Since there is a random effect in this model. I am not too sure about the
right syntax in R.
Can anyone give some suggestions?
Thank you.
Hanna
