...n which the

score on the student as a score from a prior year (for which I have no
teacher links), and the second score is from the current year and is
linked to the teacher. The model for student j in class i is:

with Var(b_i) the teacher variance component and Cov(e_{ij0},e_{ij1})

matrix in the usual linear mixed model notation has every other row
equal to a row of zeros.
