Abstract

RAWSKI, Ratal I. et al. Regression analysis in analytical chemistry. Determination and validation of linear and quadratic regression dependencies. S.Afr.j.chem. (Online) [online]. 2016, vol.69, pp.166-173. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2016/v69a20.

The theory and practice of the extended statistical evaluation for linear and quadratic regression models used for calibration were presented. Two complete examples, solved step by step were presented as a short guide. The validation of regression dependences was based on classic F-Snedecor, Lack of Fit, FIUPAC and Mandel tests.

Keywords : Correlation; regression; Lack of Fit test; Mandel test; calibration.
