depower (development version)

CRAN release: 2026-01-30

Add functions add_power_ci() and add_power_pi() for confidence intervals and prediction intervals of the power estimate, respectively.
- They add uncertainty intervals for power to the object return by power().
- Function plot.depower() will add shaded regions for the intervals.
Add functions eval_power_ci() and eval_power_pi() for confidence intervals and prediction intervals of the power estimate, respectively.
- In contrast to the add_power_*() variants, these are for planning power simulation studies.
- Assess uncertainty in hypothetical simulation-based power estimates before committing computational time to a simulation run.

CRAN release: 2025-10-22

Add functions asymptotic() and simulated() for specification of type of test.
Add argument distribution to functions:
- wald_test_nb()
- wald_test_bnb()
- lrt_nb()
- lrt_bnb()
for control of running an asymptotic, randomization, or parametric simulation test.

Fix bug where equal_dispersion argument in function lrt_nb() was not passed downstream and instead fixed to FALSE.
Fix calculation of confidence limits for mean2 and dispersion2 in functions glm_nb(), glmm_bnb(), and glmm_poisson().
