Construct Self-starting Nonlinear Models

Description

This function is generic; methods functions can be written to handle specific classes of objects. Available methods include selfStart.default and selfStart.formula. See the documentation on the appropriate method function.

Usage

selfStart(model, initial, parameters, template)

Arguments

model

a function object defining a nonlinear model.

initial

a function object, taking three arguments: mCall, data, and LHS, representing, respectively, a matched call to the function model, a data frame in which to interpret the variables in mCall, and the expression from the left-hand side of the model formula in the call to nls. This function should return initial values for the parameters in model.

parameters, template

arguments used by some methods..

Value

a function object of the selfStart class.
