unbalanced repeated measurements Anova with mixed effects
...rmat, where traveltime.1 stands for the
measured traveltime with traffic information 1, etc.
event1.mod.car<-lm(cbind("traveltime.1","traveltime.2","traveltime.3")~age*gender*kmyear,
data=event1.wide)
event1.aov.car<-Anova(event1.mod.car, idata=idata, idesign=~guidanceID)
Can I also use the aov function? But because of the unbalanced data,
this will probably not provide the right results. Is that right?
event1.aov<-aov(traveltime~guidanceID*gender*age*kmyear +
Error(userID/guidanceID), data=event1)
Thanks in advance!
