AR – Derivative-Free Nonlinear Regression

Derivative-Free Nonlinear Regression using BMDP Statistical Software Program AR

This program uses a secant method to approximate to the derivatives and places a secant plane into the response surface.

• Estimates of parameters of nonlinear function using pseudo-Gauss-Newton algorithm
• 7 built-in functions, or functions defined using BMDP instructions
• Estimates of user-specified functions of the parameters and their standard deviations
• Models defined by a system of differential equations (compartment models)
• Handles replicate data
• Linear inequality constraints on the parameters
• Plots of predicted and observed values, residuals
• Prints the serial correlation, runs test and pseudo R² for residuals
