Crossed random effects in lme
Dear all,
In the SASmixed package there is an example of an analysis of a split-plot experiment. The model is
fm1Semi <- lme( resistance ~ ET * position, data = Semiconductor, random = ~ 1 | Grp)
where Grp in the Semiconductor dataset is defined as ET*Wafer. Is it possible to specify the grouping directly some way, e.g. like
fm1Semi <- lme( resistance ~ ET * position, data = Semiconductor, random = ~ 1...
