[R-sig-ME] NAEP Data and lmer

[Doran, Harold]

Kyle:

What do you mean by "handle the plausible values thing in R". The
class.acc() function in the MiscPsycho package is essentially the same
expression used for calculating NAEP plausble values. I can send the
vignette that shows the computational details. Since for each student
you have multiple plausible values, can you give us a sense of what your
data structure looks like and how you're analyzing it in order to answer
your question?
