Regression analysis between cell-specific glutamine uptake $q_{gln}$ and specific lactate formation rate $q_{lac}$ in a CHO cell fed-batch process. (a) Regression line and (b) regression parameters from normal least squares (LS) and York regression. (c,d) One-thousand Monte Carlo regressions based on the uncertainty of the specific rates. (e,f) The obtained 68.3% confidence intervals on the regression line and the regression parameters.
