Statistical Methods for Analytical Method Comparison and Validation // 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.
