Nettet9. feb. 2024 · Linearity of the calibration curve is usually expressed through the coefficient of correlation, r, or coefficient of determination, r 2. A correlation coefficient close to unity (r = 1) is considered by some authors’ sufficient evidence to conclude that the calibration curve is linear. However, r is not an appropriate measure for the linearity.
