Description: Provides statistical methods for analytical method comparison and 
    validation studies. Implements Bland-Altman analysis for assessing agreement 
    between measurement methods (Bland & Altman (1986) <doi:10.1016/S0140-6736(86)90837-8>), 
    Passing-Bablok regression for non-parametric method comparison 
    (Passing & Bablok (1983) <doi:10.1515/cclm.1983.21.11.709>), and Deming 
    regression accounting for measurement error in both variables 
    (Linnet (1993) <doi:10.1093/clinchem/39.3.424>). Also includes tools for 
    setting quality goals based on biological variation (Fraser & Petersen (1993) 
    <doi:10.1093/clinchem/39.7.1447>) and calculating Six Sigma metrics, 
    precision experiments with variance component analysis, precision
    profiles for functional sensitivity estimation (Kroll & Emancipator (1993) 
    <https://pubmed.ncbi.nlm.nih.gov/8448849/>). Commonly used in clinical 
    laboratory method validation. Provides publication-ready plots and 
    comprehensive statistical summaries.
