Hi - Does anyone know what the variables CID and SID are in the dataMultilevelIV dataset?
The example from page 18-19 of https://cran.r-project.org/web/packages/REndo/REndo.pdf has formula1 <- y ~ X11 + X12 + X13 + X14 + X15 + X21 + X22 + X23 + X24 + X31 + X32 + X33 + (1 + X11 | CID) + (1|SID) what exactly are the (1 + X11|CID) and (1|SID) terms? does (1|SID) mean random intercepts for SID, and SID is student ID?
