Matlab Program files to accompany
Christoffersen and Diebold (1997),
"Cointegration and Long-Horizon Forecasting"

Included Files:
---------------
exgen.m		Generates data from the DGP.

mlma1.m		Evaluates the Likelihood function for an ma1 process.

exsim.m 	Computes results using mlma1.m and exgen.m,
		and saves results in exsim.mat.

osim.m		Plots results from exsim.mat


Instructions:
------------
In order to generate the results in the paper
you need to call exsim.m from the Matlab prompt.

exsim.m in turn calls exgen.m and mlma1.m. 
exsim.m will save the results in the matrix 
exsim.mat. You can change certain parameters
at the top of the exsim.m file. 

Subsequently call osim.m to generate Figures 1 
through 6 in the paper. You'll need to hit any key
iteratively to scroll through the figures.
