betaARMA 1.1.0 (2026-04-14)
Bug fixes
- Fixed incorrect computation of
ystar in
score_vector_barma(); previously the estimates were only
correct for the logit link function.
New features
- Export
loglik_barma(),
score_vector_barma(), and fim_barma() to allow
advanced user access to model internals.
Breaking changes
- Deprecate
ar = NA and ma = NA for absent
AR/MA components. Use ar = integer(0) and
ma = integer(0) or omit the arguments. Backward
compatibility is preserved in barma() with a deprecation
warning.
Improvements
- Simplify internal handling of absent AR/MA components using
vectorized operations.
- Standardize parameter order across core functions to
(alpha, varphi, theta, beta, phi).
- Set default link to
"logit" in
make_link_structure() and improve error messages for
unsupported links.
- Rename internal helper
._get_phi_start to
.get_phi_start for consistency with R conventions.
- Improve documentation of precision parameter initialization in
start_values().
