Kinkreg: Kink regression estimation

In woraphonyamaka/Kinkreg: Kink regression model of Hansen (2018)

Kink regression estimation

Description

The least sqaure estimation of kink regression model

Usage

Kinkreg(y,x,z,Call="optim")

Arguments

y	the vector of dependent variable
x	the matrix of regime-dependent independent variable
z	the matrix of exogenous variable
Call	if Call="optim" == optimization if Call="residuals" == retrun the residul series

Details

The kink regression model is the nonlinear model in which the continous function is change at the kink point.

Value

Result	the parameter estimates, standard error, t-stat and p-value
RSS	Residual sum Sqaures
