详细说明： DEAP Version 2.1 **************** A DATA ENVELOPMENT ANALYSIS PROGRAM by Tim Coelli Centre for Efficiency and Productivity Analysis School of Economics University of Queensland Brisbane, QLD 4072 Australia. email: t.coelli@economics.uq.edu.au Web: http://www.uq.edu.au/economics/cepa/ GETTING STARTED: 1. Open the WINDOWS EXPLORER program on your PC. 2. Create a new folder on your hard drive, for example called DEAP, by using the File/New/Folder option. 3. Copy ALL the files associated with DEAP into this folder, using the File/Copy option or by "drag-and-drop". 4. If the files are stored in a DEAP.ZIP file, you will then need to unzip (extract) the files by double-clicking on the zip file and extracting the contents of the zip file into the DEAP folder. FILES USED BY DEAP DEAP uses three text files when it conducts an analysis. These are: - a data file (eg. named eg1-dta.txt) - an instruction file (eg. named eg1-ins.txt) - an output file (eg. named eg1-out.txt) All of these files are text files. They can be edited using many programs. For example, NOTEPAD, WORDPAD, WORD, WORD PERFECT, etc. We suggest you use WORDPAD to view and edit these files. HOW TO RUN THE PROGRAM 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.txt (and hit the RETURN key). DEAP will only take a few seconds to complete this small example. To look at the output file (eg1-out.txt) you then simply double-click on the eg1-out.txt file name. FILE NAMES IN DOS DEAP is a DOS computer program. In DOS all file names must satisfy certain restrictions: - no more than 12 characters - no more than 3 characters after the period (".") - no more than 8 characters before the period That is, the largest possible file name has the form: XXXXXXXX.XXX Since we use text files, the file name will always have "txt" after the period. That is: XXXXXXXX.txt 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. Note that there should be no column names in the data file, only numbers. For further details see the manual. CREATING A NEW INSTRUCTION/COMMAND FILE The easiest way to create a new instruction file is to open an existing instruction file (eg. eg1-ins.txt) using WORDPAD and then save it under a new name (eg. abc2-ins.txt). This is done by using the File/SaveAs option in WORDPAD. Then you can edit the contents of this new file to suit your new analysis. CREATING DATA FILES USING EXCEL Many people store their data in Excel files. To construct a text file from an Excel file, open the file in Excel and then use the File/SaveAs option in Excel and save it as a text file. However, be sure to remove any column names first - the data file should only contain numbers. MANUAL Coelli, T.
