abstract: Provides tools for estimating the statistical power of Interrupted Time
  Series (ITS) designs, with a focus on healthcare applications. The package supports
  prospective power calculations before a study begins, and retrospective assessments
  of whether a completed study was adequately powered. It includes functions to estimate
  nuisance parameters (baseline, residual standard deviation, autocorrelation) from
  data observed before the intervention, and to estimate power via Monte Carlo simulation
  for single-site and multi-site designs. Utility functions for design optimisation
  sweeps and publication- ready plots are also provided.
