Is there a stata command that allows one to run a hybrid MLM (i.e. 𝑌𝑖𝑗 = 𝛾00+ 𝛽1 ∗ (𝑋𝑖𝑗 − 𝑋.𝑗 ̅̅̅̅) + 𝛽3 ∗ 𝑋.𝑗 ̅̅̅̅ + 𝑢0𝑗 + 𝑟𝑖𝑗) with crossed random effects? -xthybrid- doesn't seem to allow for crossed random effects, and -mixed- doesn't seem to allow hybrid. Unless I'm missing something and there is no such thing as hybrid + crossed random effects? I am new to MLM and trying to soak up whatever I can.
