Fig. 2From: Critique of the pairwise method for estimating qPCR amplification efficiency: beware of correlated data!Fit of the growth-zone points in Fig. 1 (solid) to the model of Eq. 2. Open points are calculated values. “Error” is the estimated SE. Chisq is the sum of squared residuals, from which the estimated variance is sy2 = 794.3/7 = 113.5, giving sy = 10.7Back to article page
