splitpopsurv 0.1.0 (2026-10-05)
- Initial release.
- R translation of five Stata
ml split-population survival programs
(log-logistic, Weibull, log-normal, gamma, generalized gamma).
- Corrected the log-likelihood relative to the original Stata source: the
Stata code used the marginal density where the standard hazard-based
formula requires the marginal hazard (density divided by survival),
which double-counted the survival term for every observed event. The
correction was verified by simulation against known parameters (see
docs/manual.html).
