Prism makes it quite easy to fit a model to your data.  If you are new to Prism, choose from the sample XY data sets. These not only show you how to use Prism, but also review the principles of nonlinear regression, including comparing models, identifying outliers, global fitting, and more.

Example: Fitting an enzyme kinetics curve

Example: Comparing two enzyme kinetics models

Example: Automatic outlier elimination (exponential decay)

Example: Global nonlinear regression (dose-response curves)

Example: Ambiguous fit (dose-response)

Example: Interpolating from a sigmoidal standard curve
