A puzzling thing about all this grocery uproar:
- Roughly 6-8% of the median US household's income is spent on groceries, so like $4000 a year
- Even if applied to literally all groceries a person buys, a 15% discount is like $600 a year, which honestly is... kind of pathetic?
I've made a little blog post about using partial pooling to carefully estimate interaction effects for linear models. Here it's for estimating alpha in factor models, but the technique is fairly general and can be improved on. May edit in the future.

The novelty for interactions is that there are multiple ways to refer to similarity (a lattice of ways), which each give a new mean datapoint, so I added a simple heuristic fix to keep everything working,

this is a 1996 guide on how to help someone use a computer. it’s strikingly resonant with ‘how to be a parent’, or really ‘how to help anyone with anything’. a nice example of “the universal within the particular”
