Calculate Overall Survival or Recurrence-Free Survival for breast cancer patients, using 'NHS Predict'. 
            The time interval for the estimation can be set up to 15 years, with default at 10.
            Incremental therapy benefits are estimated for hormone therapy, chemotherapy, trastuzumab, and bisphosphonates.
            An additional function, suited for SCAN audits, features a more user-friendly version of the code, with fewer inputs, but necessitates
            the correct standardised inputs.
            This work is not affiliated with the development of 'NHS Predict' and its underlying statistical model.

            A small dataset of 50 fictional patient observations is provided for the purpose of running examples with the main two functions,
            and an additional dataset is provided for running example with the dedicated SCAN function.

Provides tools for importing, harmonising, cleaning, analysing,
    benchmarking and visualising National Health Service (NHS) England
    Cancer Waiting Times data. The package supports national performance
    monitoring, provider-level benchmarking and cancer pathway comparisons
    through key performance indicator summaries, provider filtering,
    clustering analyses, mixed-effects regression models, variance
    decomposition, intraclass correlation coefficient estimation, adjusted
    provider performance estimation and sensitivity analyses. Functions are
    included for exploratory analysis, publication-ready visualisations and
    spreadsheet exports, supporting reproducible health services research,
    cancer services evaluation, quality improvement and assessment of
    waiting-time performance across healthcare organisations. Mixed-effects
    modelling functionality is based on Bates et al. (2015)
