In nlr: Nonlinear Regression Modelling using Robust Methods

Description

Convert fktlist objects defined by Bunke et.al to nl.form. It calculate gradient and hessian using derive3 function.

Usage

convfkt2nlform(fktlistex, namesdata = NULL)

Arguments

fktlistex	fktlistex object include fkt, par, p, ccode, lambda, case, inv, name, defined by Bunke et al (1998)
namesdata	Name of data, is not functional now, used for feature development.

Details

fktlist defined by Bunke et al (1998) convfkt2nlform function convert this object to nl.form object.

Value

nl.fomr object with gradient and hessian attributes.

Note
