"β¦when estimating a #causalEffect from data with a #multilevel structure, it is necessary to allow both the intercepts & effects to vary along each grouping structure. In practice, this is a challenge, 1st because we know of no #textbook that offers this recommendation; 2nd because including additional variance components to a model can make it less stable to fitβ¦ 3rd because modeling choices will still ariseβ¦"
