Rtauchen {Rtauchen}

Rtauchen

Description

This function generates a matrix of transition probabilites of a finite-state Markov chain that mimics an AR(1) process with persistence parameter llamda, standard deviation ssigma and a fixed parameter m.

Usage

Rtauchen(ne, ssigma_eps, llambda_eps, m)

Arguments

ne

Number of points of the grid of the finite-state Markov chain that mimics the AR(1) process

ssigma_eps

Standard deviation of exogenous shock in the AR(1) process

llambda_eps

Persistence parameter of the AR(1) process

m

Tauchen parameter for the width of the process (number of standard deviations of the AR(1) process covered by the grid)

Details

See Tauchen (1986) for details.

Value

A matrix with the corresponding to the transition matrix of the finite-state Markov chain that approximates the AR(1) process
