bad_classification: Detect poor performers

Description Usage Arguments Value

View source: R/preprocessing.R


Basic check: find people who are classifying the endpoints inconsistently or inaccurately. One way to measure quality is by the fitted log-odds of /p/ response at 0 and 70 ms (continuum endpoints, for all intents and purposes). This measures how consistent people are (in a smoothed way) at the ends of the continuum. Intuitively, we want to throw out anyone who doesn't ever consistently get both /b/ and /p/. So we'll set a cutoff of 80 logodds of a /p/ response greater than about 1.4 ('qlogis(0.8)') at the /p/ end of 70ms and less than -1.4 at the /b/ end.
