mc.paba

upper triangular matrix of slopes for all
 point combinations. Slopes in radian.

angM

measurement values of reference method

numeric value specifying the 100(1-alpha)
 confidence level

alpha

should algorithm assume positive
 correlation, i.e. symmetry around slope 1?

posCor

should confidence intervals be computed?

calcCI

angular measure of pairwise slopes
 (see <code><a rd-options="" href="/link/mcreg?package=mcr&version=1.2.1" data-mini-rdoc="mcr::mcreg">mcreg</a></code> for details). <code>"radian"</code> -
 for data sets with even sample numbers median slope is
 calculated as average of two central slope angles.
 <code>"tangent"</code> - for data sets with even sample numbers
 median slope is calculated as average of two central
 slopes (tan(angle)).

slope.measure

This package provides regression methods to quantify the relation between two measurement methods. In particular it addresses regression problems with errors in both variables and without repeated measurements. The package provides implementations of Deming regression, weighted Deming regression, and Passing-Bablok regression following the CLSI EP09-A3 recommendations for analytical method comparison and bias estimation using patient samples.
