Hi all, Does anyone have better ideas to speed up the matrix construction of the random effects in the mixed effect model or joint models? As shown below, I currently wrote my Stan function by calling the random effect per observation per subject. This is really time-consuming in the computation up…

How to speed up the construction of the random effects in joint models?
