FOR ADVICE ON HOW TO USE THIS PROGRAM, REFER TO THE USER'S GUIDE: Coelli, T. (1996) 'A Guide to DEAP Version 2.1: A Data Envelopment Analysis (Computer) Program', CEPA Working Paper 96/08, Centre for Efficiency and Productivity Analysis, University of New England. A COPY OF THIS GUIDE (IN PDF FORMAT) IS PROVIDED IN THE FILE: DEAP.PDF. ONE CAN VIEW OR PRINT THIS DOCUMENT USING THE (FREE) ADOBE ACROBAT READER WHICH CAN BE DOWNLOADED FROM THE ADOBE WEB SITE AT: http://www.adobe.com/prodindex/acrobat/readstep.html MACHINE REQUIREMENTS: 386 or higher math co-processor 4MB RAM (8MB recommended) GETTING STARTED: DEAP can be run from a floppy drive, but it is best to run it from your hard drive. This can be done using DOS commands or using FILE MANAGER in WINDOWS. DOS commands: ------------- 1. Create a directory on your hard disk, say called DEAP, by typing: MD \DEAP 2. Copy all files from the floppy by typing: COPY A:*.* \DEAP (assuming the floppy is in your A: drive) 3. Change into the DEAP directory by typing: CD \DEAP 4. One can then use a word processor or text editor such as DOS EDIT to look at the example data and instruction files. For DOS EDIT you would type EDIT EG1.INS or EDIT EG1.DTA etc. (see below for info on data file structure). 5. To practice running DEAP type DEAP The program will then ask for an instruction file name. Type in EG1.INS DEAP will then only take a few seconds to complete this small DEA example. You can then look at the output file (EG1.OUT) using, for example, DOS EDIT by typing EDIT EG1.OUT 6. For further detail on using DEAP see the User's Guide. FILE MANAGER commands: ---------------------- 1. Use the FILE/CREATE DIRECTORY menu items to create a DEAP directory on your hard drive. 2. Use drag-and-drop to copy the DEAP program files from your floppy disk to the DEAP directory. 3. Use the FILE/ASSOCIATE menu items to associate your favourite Windows text editor (e.g., NOTEPAD) with the file extensions ".INS", ".DTA" and ".OUT". This will allow you to edit these files (or view them) by simply double-clicking on the file names. You only need to set the associations once and then Windows will store this association information. 4. To check that the associations have worked you can double-click on EG1.INS and EG1.DTA (see below for info on data file structure) to look at their contents. 5. To practice running DEAP double-click on the DEAP.EXE file name. The program will then ask for an instruction file name. Type in EG1.INS (and hit the RETURN key). DEAP will only take a few seconds to complete this small DEA example. To look at the output file (EG1.OUT) you then simply double-click on the EG1.OUT file name. 6. For further detail on using DEAP see the User's Guide. DATA FILE STRUCTURE All data, instruction and output files are text files. In the data file the output columns are listed first followed by the input columns (left to right across the file). If you are doing a cost eff DEA the input price columns are listed to the right of these. If you are doing Malmquist DEA all observations for year 1 are listed first, then those for year 2, and so on down the file. For further details see the User's Guide.
