A set of Splus (or R) functions and programs to estimate the parameters of a non-linear regression model over a given set of observations.
Several additional tools are included: plotting functions, functions to process series of estimations, calculate confidence intervals and confidence regions for parameters and functions of parameters, and process calibration study. The description of the models can be provided by using a symbolic syntax.
To use without Splus nor R, see nls2CThis package is developed in the MaIAGE Lab. of INRA - Jouy-en-Josas, France.
