Description: Methods for assessing agreement between repeated
        measurements obtained by two or more methods using the
        longitudinal concordance correlation coefficient (LCC).
        Polynomial mixed-effects models (via 'nlme') describe how
        concordance, Pearson correlation and accuracy evolve over time.
        Functions are provided for model fitting, diagnostic plots,
        extraction of summaries, and non-parametric bootstrap
        confidence intervals (including parallel computation),
        following Oliveira et al. (2018)
        <doi:10.1007/s13253-018-0321-1>.
