Michael P. Clements and David F. Hendry, "Forecasting in Cointegrated Systems", Journal of Applied Econometrics, Vol. 10, No. 2, 1995, pp. 127-146. Two files are supplied. The data for the simulation results reported in Tables 1 and 3 can be generated from the GAUSS program "mpc_dfh.prg". (The data in Table 2 are calculated from Table 1). The two series on which the empirical illustration in Section 8 is based are Rn and v, made available in the human-readable file "sect8.dat". Both these files are contained in the file mpc_dfh.zip.
