An example of functional relationship fitting in analytical science. Comment on ‘Modification of Winkler's method for determination of dissolved oxygen concentration in small sample volumes’ by A. Shriwastav, G. Sudarsan, P. Bose and V. Tare

[摘要] In a recent issue of Analytical Methods, Shriwastav et al. (Anal. Methods, 2010, 2, 1618) compared the performance of a modified method for determining dissolved oxygen in water with the standard Winkler's method. They wisely avoided using simple regression for comparing the results as a whole, but some may believe they missed an opportunity for using functional relationship fitting, a method that addresses bivariate data with error on both variables...
