However, my real questions is: How DF = 3209 and 22 are calculated? I
follow
the book by Pinheiro and Bates (2000, p.91),
Q = 1
mo=1 because I have intercept in model
m1=26 groups
m2=3237 observations
p0=1

Are these coefficients are the level-2, and thus, DF for testing dep's
should be (J-Q2_1=26-1-1=24). Why I get the number 3206, especially for
depD27 depD35 and depD50.
