%description
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.
