kern: Kernel regression with options for residuals and gradients.

Description

Function to run kernel regression with options for residuals and gradients asssuming no missing data.

Usage

kern(dep.y, reg.x, tol = 0.1, ftol = 0.1, gradients = FALSE, residuals = FALSE)

Arguments

dep.y

Data on the dependent (response) variable

reg.x

Data on the regressor (stimulus) variables

tol

Tolerance on the position of located minima of the cross-validation function (default =0.1)

ftol

Fractional tolerance on the value of cross validation function evaluated at local minima (default =0.1)

gradients

Make this TRUE if gradients computations are desired

residuals

Make this TRUE if residuals are desired

Value

Creates a model object `mod' containing the entire kernel regression output. Type names(mod) to reveal the variety of outputs produced by `npreg' of the `np' package. The user can access all of them at will by using the dollar notation of R.
