Now I want to create lagged (previous-week) variables for both X and Y and add them as control variables. I have seen in a paper that while lagged Y was grandmean centered,...

The variance (estimate) of Level 2 increases when new Level 1 predictors are added in a regression equation (all as predictors of a Level 1 outcome). I usually have this when all predictors in the equation are at Level 1. I'm quite puzzled by ...
