Step-by-Step Examples - Nonlinear Regression

Fitting an enzyme kinetics curve

Comparing two enzyme kinetics models

Interpolating from a sigmoidal standard curve

Automatic outlier elimination (exponential decay)

Global nonlinear regression (two dose-response curves)

Dependency and ambiguous fits (dose-response curves)

Detailed help to fit built-in equations

Prism comes with dozens of built-in equations to use in nonlinear regression (of course you can also add your own equations). For each of the built-in equations, we provide a detailed description with step-by-step instructions. Here are a few examples:

Equation: log(agonist) vs. response -- Variable slope

Equation: log(inhibitor) vs. normalized response

Equation: One phase exponential decay

Equation: Competitive binding - One site - Fit Ki

Equation: Receptor binding - Dissociation kinetics

Equation: Mixed-model enzyme inhibition

Equation: Gaddum/Schild EC50 shift
