AS_bounds {RegCombin}

This function finds the boundary of the identified set in one specified direction using the AS test and Newton's method.

Description

This function finds the boundary of the identified set in one specified direction using the AS test and Newton's method.

Usage

AS_bounds(start, Yp, Xb, N_max = 30, tol = 10^(-4), tuningParam = NULL)

Arguments

start

the starting points for the bissection method

Yp

the observations of the outcome variable.

Xb

the observations of the noncommon regressor (possibly conditional on Xc).

N_max

the maximal number of iterations. Default is 30.

tol

the tolerance of the method. Default is e-4.

tuningParam

the list of tuning parameters. For the details see the function "test" in the package RationalExp.

Value

a list containing, in order: - the value of estimated radial function in this direction - value of the objective function - the number of iterations
