Fitting curves to data using nonlinear regression: a practical and nonmathematical review HARVEY J. MOTULSKY AND LENNART A. RANSNAS Department of Pharmacology, University of Calfornia, San Diego, La Jolla, California 92093, USA parameters. Before discussing nonlinear regression, ABSTRACT however, we will first review the other methods used for fitting curves to data. Many types of data are best analyzed by fitting a curve using nonlinear regression, and computer programs Linear regression of transformed data that perform these calculations are readily available. Like every scientific technique, however, a nonlinear Linear regression is familiar to all scientists. Data are regression program can produce misleading results graphed so that the x axis represents the independent when used inappropriately. This article reviews the use variable and they axis represents the dependent variable. The line drawn
