Linearity experiment

Nettet1. jun. 2014 · The linearity of a PCR reaction is expressed as the correlation coefficient (R 2) of the curve obtained by linear regression analysis (ENGL, 2008). The robustness of a method is a measure for its capacity to remain unaffected ( i.e. to provide a similar result) by small but deliberate changes in the experimental conditions as compared to the … Nettetof testing for non-linearity in the context of threshold models has been studied by Tsay (1989), Chan (1990, 1991), Chan and Tong (1990), Hansen (1996, 1997), and Caner …
