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. Weighted Deming regression is also
  now implemented for multiple instruments. The following reference provides further
  information on mathematical derivations and applications. Hawkins, D.M., and J.J.
