Installation instructions: create a directory, for example TST, and decompress all files into this directory by running TSTMATLAB.EXE. The following files should be in this directory: ANALTS.EXE, MAIN.EXE, MIPAT.EXE, README.TXT, SEATS.BAT, SEATS.ITR, SERIE, SERIE.PAT, SERIE.SPA, SERIE.STS, SERIE.TRC, SERIE.TRM, TRACE.BAT, TRACEEX.EXE, TRAMO.BAT, TS.BAT, TST.BAT, and several MATLAB files with extension M. There should be the following subdirectories: EXAMPLES, FDESC, GNUPLOT, GRAPH, MATLAB, OUTPAT, OUTPUT, SERIES, SPECTAN, SPECTRC, SPECTRM, TRACEMAN, TSMAN, and TSTMATLABMAN. TRAMO, SEATS and TRACE can be run in the MATLAB environment as described in the manual TSTMATLAB located in the directory TSTMATLABMAN. TRAMO and SEATS are described in the manuals TS-INST97C.PDF and CHANGPRO.PDF located in the directory TSMAN. Some examples for TRAMO and SEATS are in the directory EXAMPLES. TRACE (Trend and Cycle estimation) is described in the manual TRACEMAN.PDF, located in the directory TRACEMAN. Some examples of input files for TRACE are in the directory EXAMPLES. Some specifications for bandpass filters to apply to yearly, quarterly and monthly series are in the directory SPECTRC. Some remarks on the DOS versions of TRAMO, SEATS, TRACE and PAT: The versions of TRAMO and SEATS are reliable DOS versions that comply with the 1997 manual of these programs with three exceptions: 1) The programs are in the same directory. 2) The input files are SERIE.TRM and SERIE.TST, and the output files have the extension TRM and TST. 3) In the output of SEATS some data are printed with more decimal places. Apart from running TRAMO, SEATS and TRACE using TSTMATLAB, these programs can also be run in the operating system environment, as described in the their manuals. To run TRAMO, type tramo. To run SEATS, type seats. To run TRACE, type trace. To run both TRAMO and SEATS, type TS. To run TRAMO, SEATS and TRACE, type TST. The input file for TRACE is SERIE.TRC. The output from TRAMO and SEATS is written in the directory OUTPUT, with the extensions described in 2) above, and in the directory GRAPH, as described in the manuals of these programs. The output from TRACE is written in the directory GNUPLOT (the data in two columns, one for the trend and one for the cycle, with extension DAT) and in the directory OUTPUT (the program output with extension TRC). Also, some instructions for graphics can optionally be written in the directories MATLAB (for MATLAB graphics with extension M) and GNUPLOT (for gnuplot graphics with extension GNP). Program PAT can be run by typing mipat and then intro. The TRACE program creates input files for PAT automatically. The version of PAT is that of OECD 1995, modified to handle input and output files differently. The input for PAT should be in the file SERIE.PAT. The output from PAT is written in the directory OUTPAT. There are two files, one with extension TXT and the other with extension DAT. Make sure that the file LISTA.DAT exists in the FDESC subdirectory before executing PAT. Otherwise this program will not run and an error message will be displayed.
