  • Fitting data with nonlinear regression -- Clarify your goal. Is nonlinear regression the appropriate analysis? -- Prepare your data and enter it into the program -- Choose your model -- Decide which model parameters to fit and which to constrain -- Choose a weighting scheme -- Choose initial values -- Perform the curve fit and interpret the best-fit parameter values -- Preparing data for nonlinear regression -- Avoid Scatchard, Lineweaver-Burk, and similar transforms whose goal is to create a straight line -- Transforming X values -- Don't smooth your data -- Transforming Y values -- Change units to avoid tiny or huge values -- Normalizing -- Averaging replicates -- Consider removing outliers -- Nonlinear regression choices -- Choose a model for how Y varies with X -- Fix parameters to a constant value? -- Initial values -- Weighting -- Other choices -- The first five questions to ask about nonlinear regression results -- Does the curve go near your data? -- Are the best-fit parameter values plausible? -- How precise are the best-fit parameter values? -- Would another model be more appropriate? -- Have you violated any of the assumptions of nonlinear regression? -- The results of nonlinear regression -- Confidence and prediction bands -- Correlation matrix -- Sum-of-squares -- R[superscript 2] (coefficient of determination) -- Does the curve systematically deviate from the data? -- Could the fit be a local minimum? -- Troubleshooting "bad" fits -- Poorly defined parameters -- Model too complicated.
