%description
Predicts Rasch item difficulty from item features (text embeddings from
any model, template family, content metadata) by ridge regression (Hoerl
and Kennard, 1970, <doi:10.1080/00401706.1970.10488634>) with honest
out-of-sample uncertainty, uses the predictions as robust informative
priors to calibrate new items from small pretest samples, in the spirit of
using collateral information in calibration (Mislevy, Sheehan and
Wingersky, 1993, <doi:10.1111/j.1745-3984.1993.tb00422.x>), plans the
pretest sample size needed for a target precision, and diagnoses item
families whose predictions cannot be trusted.
