Changes in version 2026.1.30.999                    

Bug Fixes

  - Remove trailing slash on void elements to pass CRAN vnu HTML check.

               Changes in version 2026.1.30 (2026-01-30)                

New Features

  - 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.

Other Updates

  - General improvements in documentation.

               Changes in version 2025.10.21 (2025-10-22)               

New Features

  - 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.

Bug Fixes

  - 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().

Other Updates

  - Add and update tolerances in tests.
  - General improvements in documentation.
  - General improvements in code.

               Changes in version 2025.1.20 (2025-01-23)                

  - Fix typos in documentation.
  - Fix test error resulting from ATLAS numerical differences.
