Hi there,

we would like to calculate MLM to differentiate the effects of Level-1 and Level-2 predictors on a Level-1 DV. In our model we use individual, aggregated individual and context variables.

For me it is still unclear, which centering method (grand mean and/or group mean) is appropriate in this case.

Any suggestions?

Thanks,

Michael
