Software
As part of its research activities, CEPA develops and maintains several state-of-the-art statistical software packages. This software can be used to obtain measures of productivity and efficiency using several different methodologies. Four pieces of free computer software currently available from CEPA are as follows:
DEAP Version 2.1
Deap (Ver 2.1) used to conduct data envelopment analysis (DEA).
DPIN Version 3.1
DPIN™ (Ver 3.1) used to compute TFP indices and decompose them into a measure of technical change and various measures of technical, scale and mix efficiency change. The Standard Edition is free. A Professional Edition can be obtained by paying an annual license fee.
Frontier Version 4.1
Frontier (Ver 4.1) used to estimate stochastic frontier models.
TFPIP Version 1.0
TFPIP (Ver 1.0) used to construct binary and transitive multilateral TFP indices based on Fisher and Tornqvist indices.
Testimonials
"I am a PhD student of applied economics at the University of Illinois at Urbana-Champaign. I am currently working on efficiency estimation and public economics, and I found your software very useful. In particular, I have been using DEAP 2.1 to estimate efficiency for local governments."
- Jhorland Ayala, University of Illiois
"I wanted to inform you that I have successfully used your software for scientific research, namely DEAP and Frontier. Thank you very much for your support."
- Professor Vítor Martinho, Polytechnic Institute of Viseu
A Data Envelopment Analysis (Computer) Program
This page describes the computer program DEAP Version 2.1 which was written by Tim Coelli. This program is used to construct DEA frontiers for the calculation of technical and cost efficiencies and also for the calculation of Malmquist TFP Indices.
The program has three principle DEA options:
- Standard CRS and VRS DEA models that involve the calculation of technical and scale efficiencies (where applicable)
- The extension of the above models to account for cost and allocative efficiencies
- The application of Malmquist DEA methods to panel data to calculate indices of total factor productivity (TFP) change; technological change; technical efficiency change and scale efficiency change
All methods are available in either an input or an output orientation (with the exception of the cost efficiencies option). The output from the program includes, where applicable, technical, scale, allocative and cost efficiency estimates; slacks; peers; and TFP indices.
The program is compiled using a Lahey F77LEM/32 compiler for an IBM compatible PC. The program package includes the executable program; data files for four simple examples; and a 47 page user’s guide (in pdf format).
If you wish to obtain a copy of the program you can download the zip file DEAP-xp1.zip which contains all the necessary files.
If you obtain a copy of the program you are advised to send some brief email to Tim Coelli at t.coelli@economics.uq.edu.au so that he can advise you of any bugs or new versions.
If you have any technical questions regarding the use of this computer program you can contact Tim Coelli by email at t.coelli@economics.uq.edu.au. Brief questions (involving less than 10 minutes of time) will be answered as quickly as is possible. A consultancy service is available for those who have more lengthy enquiries. Consultancy fees will be provided on request.
Conducting data envelopment analysis in DEAP
DPIN™ (Ver 3.1) is software for Decomposing Productivity Index Numbers into measures of technical change and various measures of efficiency change.
The program can be used to analyse the productivity of any multiple-input multiple output firm operating in any market environment. Different editions of the software can be obtained by paying the annual license fees specified in Table 1 below. If a person or entity obtains the Standard Edition then the functionality of the software will be limited to the extent indicated below:
| Features | Standard | Professional |
|---|---|---|

| Paasche, Laspeyres, Fisher and Lowe Indexes | - | Yes |
| TFP Efficiency | Yes | Yes |
| Technical Efficiency | Yes | Yes |
| Scale Efficiency | Yes | Yes |
| Mix Efficiency | Yes | Yes |
| Allocative Efficiency | - | Yes |
| Shadow Prices | - | Yes |
| Technical Change Options | Yes | Yes |
| Returns to Scale Options | Yes | Yes |
| Maximum Number of Observations | 5000 | 5000 |
| Annual License Fee - Academic | FREE | AUD 495 Ex-GST |
| Annual License Fee - Commercial | FREE | AUD 995 Ex-GST |
The Standard Edition of DPIN™ Version 3.0 is designed for use on computers that run Microsoft Windows operating systems. To install the Standard Edition, download the file DPIN™3.0S.zip and extract the contents into any directory. No payment is required for the Standard Edition.
The Professional Edition of DPIN™ Version 3.1 is also designed for use on computers that run Microsoft Windows operating systems, but cannot be used on computers that run non-English versions of Microsoft Windows or have dual languages displayed. To install and obtain a license for the Professional Edition:
- Download the zip file DPIN™3.1P.zip and extract the contents into any directory on the computer where the software will be installed.
- Run the file GetSystemID.exe from the directory used in Step 1 to obtain a 12-character machine-specific system ID.
- Complete the License Payment Form and then fax, post or scan and email the completed form to the address given on the form.
- Once payment has been processed you will receive a file called license.key by email. Save this file in the directory used in Step 1 and the program will be ready to run on that computer. The software will not run on any other computer.
First-time users are encouraged to first download and install the Standard Edition and conduct tests to confirm that the software is compatible with their hardware and operating system. Technical questions regarding the use of the software should be directed to c.odonnell@economics.uq.edu.au. Brief questions (involving less than 10 minutes of time) will be answered as quickly as possible. A consultancy service is available for those who have more lengthy enquiries. Consultancy fees will be provided on request.
FRONTIER is used to obtain maximum likelihood estimates of the parameters of a variety of stochastic production and cost frontiers, and estimates of mean and individual technical or cost efficiencies.
The program can accommodate:
- cross-sectional or panel data
- half-normal or truncated normal distributions
- any functional form which is linear in parameters
- time-invariant or time-varying efficiencies
- inefficiency effects can be explicitly influenced by a number of firm-specific factors.
The program is compiled using a Lahey F77LEM/32 compiler for an IBM compatible PC. Persons who request a copy of the program receive the executable program file; the Fortran source code; some examples to practice with; and a 32 page user’s guide (in pdf format).
If you wish to obtain a copy of the program you can download the zip file FRONT41-xp1.zip which contains all the necessary files.
