Description: 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.
