3R – Nonlinear Regression

Nonlinear Regression using BMDP Statistical Software Program 3R

For built-in and user specified functions, 3R uses analytically exact partial derivatives in the iterative process to estimate parameters. A Gauss-Newton algorithm is used which essentially fits a plane tangent to the response surface.

• Estimates of parameters of nonlinear function via Gauss-Newton algorithm
• 7 built-in functions, or functions defined using BMDP instructions
• Exact linear constraints on the parameters
• Plots of predicted and observed values, residuals
• Sum of squares profile plots of paramters, with confidence intervals
• Durbin-Watson statistics
