I'm hoping that this is a relatively easy question for someone familiar with
the lme4 package.
I'm accustomed to using HLM software and writing a simple 2 level [null]
equation like this:
L1 - Yij = b0 + e
L2 - b0 = B00 + u0
The following command in R provides results that are identical to the HLM
program.
results <- lmer( Y ~ 1 |id , PanelData4)
I can't seem to find any examples on-line nor in the help about how to write
the lmer4 formula that contains two predictor variables at level 1 with
fixed slopes.
L1 - Yij = b0 + b1(x) + b2(z) + e
L2 - b0 = B00 + u0
b1 = B10
b2 = B20
Can someone give me an example?
Thanks
Jeff
