SPA curvefit.com was created by GraphPad Software, Inc. Send comments or questions to the author of these pages, Dr. Harvey Motulsky, president of GraphPad Software. In April 2003, GraphPad released Prism 4 and published Fitting Models to Biological Data using Linear and Nonlinear Regression. This book includes all the information that comprises curvefit.com, and much more. You can read this book as a pdf file. 
Introduction to regression Welcome to curvefit.com! The difference between linear and nonlinear regression Avoid Scatchard, Lineweaver-Burk and similar transforms Linear regression Fitting linear data with nonlinear regression Other kinds of regression Fitting a curve without choosing a model Nonlinear regression Introduction to nonlinear regression Choices to make when fitting data with nonlinear regression Why a computer program cannot pick a model for you Classic equations commonly used by biologists How models are derived Sum-of-squares as a measure of goodness-of-fit in nonlinear regression Weighting methods How nonlinear regression works Nonlinear regression with Prism Nonlinear regression with Prism Initial values with Prism Fixing parameters to constant values Method options with Prism Output options with Prism Default options for nonlinear regression Importing equations and the equation library User-defined equations Constraining variables in user-defined equations How to fit different portions of the data to different equations How to simulate a theoretical curve Interpreting the results of nonlinear regression Approach to interpreting nonlinear regression results Do the nonlinear regression results make sense? How certain are the best-fit values? How good is the fit? Does the curve systematically deviate from the data? Could the fit be a local minimum? Have you violated an assumption of nonlinear regression? Have you made a common error when using nonlinear regression? Comparing two curves Comparing the fits of two models Comparing fits to two sets of data (same equation) The distributions of best-fit values Why care about the distribution of best-fit values Using simulations to determine the distribution of a parameters Example simulation 1. Dose-response curves. Example simulation 2. Exponential decay.
