Slug: kennethkhoocy-pyfixest-cupy64-absorbed-regressors
Category: automation
Description: pyfixest demeaner_backend="cupy64" (including its CPU fallback when cupy is
absent) is NOT numerically identical to the default numba backend and does
NOT drop fully-absorbed/collinear regressors the same way. Use when: (1)
adding demeaner_backend="cupy64" to existing pf.feols/fepois calls changes
the printed coefficient table, (2) a regression report suddenly gains rows
with absurd estimates (e.g. coef 435.8, SE 7106) for controls absorbed by
the fixed effects, (3) diffing outputs before/after a backend change, or
(4) anything parses a pyfixest text report by line position.
