Hello all:
I've read the document named "A Brief Introduction to R, the multilevel package and the nlme package".
At p68, one can transform the dataset to the required format by using "make.univ".
I wanna know,how the new variable "MULTDV" is calculated(can you show me the formula if possible please?)?And what's the usage of this new variable in the following analysis?
 
 
Thanks a lot!
 
My best.
