Changelog

Version 1.2.0

  • Improvements to batss.glm:
    • interim = NA now specifies a fixed (non-adaptive) design with a single look at the maximum sample size N
    • a warning is issued when RAR is non-NULL and interim = NA, as response-adaptive randomisation has no effect in a fixed design
  • Bug fixes to batss.glm, batss.combine, summary.batss, plot.batss and internal functions, including a fix to eff.trial.control and fut.trial.control being ignored in trial-level stopping decisions
