Multilevel mixed-effects linear model

JOADUTWUM — Mon, 11 Oct 2021 05:27:10 GMT

Dear All;

I would be glad if you could help me out on this:

I found this model in a paper which I want to replicate:

Yijkd = (B0+B0i+B0ij+B0ijk) + (B1+B1i+B1ij+B1ijk)*xijkd+eijkl

Would be happy to get a head start in SAS syntax.

Thank you.
