abstract: 'Weighted Deming regression, also known as ''errors-in-variable'' regression,
  is applied with suitable weights. Weights are modeled via a precision profile; thus
  the methods implemented here are referred to as precision profile weighted Deming
  (PWD) regression. The package covers two settings – one where the precision profiles
  are known either from external studies or from adequate replication of the X and
  Y readings, and one in which there is a plausible functional form for the precision
  profiles but the exact (unknown) function must be estimated from the (generally
  singlicate) readings. The function set includes tools for: estimated standard errors
  (via jackknifing); standardized-residual analysis function with regression diagnostic
  tools for normality, linearity and constant variance; and an outlier analysis identifying
  significant outliers for closer investigation. The following reference provides
  further information on mathematical derivations and applications. Hawkins, D.M.,
  and J.J. Kraker (2026). ''Precision Profile Weighted Deming Regression for Methods
  Comparison''. The Journal of Applied Laboratory Medicine 11, 379-392 <https://doi.org/10.1093/jalm/jfaf183>.
  Weighted Deming regression is also now implemented for multiple instruments , as
  set out in Hawkins, D.M., and J.J. Kraker (2026). ''Multiple Instrument Methods
  Comparison by Precision weighted Deming Regression'', on Arxiv <https://doi.org/10.48550/arXiv.2607.11776>.
  The “multi” functions refer to the multiple instrument analysis, and the "PWD" functions
  refer to the two-instrument.'
