title: 'ballast: Stress-Test a Pre-Specified Mixed Model for Repeated Measures'
version: 0.6.1
doi: 10.5281/zenodo.23427834
abstract: Refits one pre-specified mixed model for repeated measures (MMRM) under
  families of data and analytic perturbations (covariance structure, degrees-of-freedom
  method and variance estimator, covariate set, analysis population, alternative analysis
  data sets, leave-one-out deletions, crossed specification grids, re-randomisation
  tests, delta-adjusted and reference-based multiple imputation, and alternative estimators)
  and judges every refit against the pre-specified estimate, confidence interval and
  p-value. Classifies the result as robust, sensitive or fragile, with a separate
  flag for marginal significance, and estimates by simulation the probability that
  a planned design gives a significant and robust result. Fitting uses 'mmrm' (Sabanes
  Bove et al., 2024, <https://openpharma.github.io/mmrm/>) with 'SAS' 'PROC MIXED'
  conventions for the least-squares-mean contrast, Kenward-Roger adjustment and the
  corrected Akaike criterion. Reference-based multiple imputation follows Carpenter,
  Roger and Kenward (2013) <https://doi.org/10.1080/10543406.2013.834911> and was
  checked against 'rbmi' (Gower-Page, Noci and Wolbers, 2022) <https://doi.org/10.21105/joss.04251>.
