number crunching

formerly msc @ lse stats, surveys @ us census
But that doesn’t justify using unweighted responses!

These are the unweighted proportions for years to graduation from the FIRE dataset: would Kaufmann infer that the true proportion of college students who are about to graduate surged by 74% and then collapsed by 30% since 2020?

In response to this follow up from Kaufmann, I updated my post today to clarify that I don’t think the weighted or unweighted estimates are a good answer to this question

hey thanks (1) for saying so, I appreciate it (2) in a roundabout way, for your help--I haven't used my personal site for much but I remember referencing at least one post of yours when I first put it up

There are a number of issues with this analysis but I found one that I haven't seen anyone else mention: Kaufmann estimates gender ID from the FIRE data without using the survey weights

When the weights are used as designed, the evidence for his core claim disappears

You can’t fathom the difference between 0.002 and 1. This chart is to scale.

It’s so dark to see people grind all of this into content of the same flavor as everything else. “Laughing til my head comes off, who’s in a bunker,” etc
