A Pareto chart illustrating the significance of each variable. B Plot of correlation of the predicted and actual camptothecin yield of A. terreus. C Box-Cox power transform. Plot of standardized effect (D), internal standardized residuals (E) with the normal probability. F Plot of standardized effect with the half-normal probabilityBack to article page
