Description: Provides methods for estimating minimal important change (MIC)
    and interpretation thresholds for multi-item questionnaires and single-item continuous or ordinal
    measures. Methods include predictive modelling, adjusted predictive
    modelling, improved adjusted predictive modelling using anchor reliability,
    confirmatory factor analysis for anchor reliability, longitudinal
    confirmatory factor analysis for MIC estimation, longitudinal confirmatory
    factor analysis-based MIC estimation for single-item measures, and
    confirmatory factor analysis-based threshold estimation for single-item and
    multi-item measures. Implemented methods include those developed by
