summary.sigma_metric

Provides a detailed summary of the sigma metric calculation,
including the formula and interpretation scale.

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.
