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.
