In particular, - Equations 8.26 and 8.28 were combined in order to yield a general treatment - of inverse prediction for univariate linear models, taking into account - weights that have been used to create the linear model, and at the same - time providing the possibility to specify a precision in sample measurements - differing from the precision in standard samples used for the calibration. - This is elaborated in the package vignette.</p> - - </div> - - <div class="Note"> - <h2>Note</h2> - - <p>The function was validated with examples 7 and 8 from Massart et al.
