Data Envelopment Analysis: Critique and Extensions.
Peer reviewed Peer reviewed
Sexton, Thomas R.; And Others – New Directions for Program Evaluation, 1986
Recent methodological advances are described that enable the analyst to extract additional information from the data envelopment analysis (DEA) methodology, including goal programming to develop cross-efficiencies, cluster analysis, analysis of variance, and pooled cross section time-series analysis. Some shortcomings of DEA are discussed. (LMO)

The Challenge of Error Trapping: Catching Those Incorrect Inputs.
Summers, Mike K.; Willett, John B. – Creative Computing, 1980
The need for traps, a program routine which checks the validity of the user's response to the computer's request for input, in Computer Assisted Learning Packages, is discussed. Several example traps are described. (MK)

The Methodology of Data Envelopment Analysis.
Peer reviewed Peer reviewed
Sexton, Thomas R. – New Directions for Program Evaluation, 1986
The methodology of data envelopment analysis, (DEA) a linear programming-based method, is described. Other procedures often used for measuring relative productive efficiency are discussed in relation to DEA, including ratio analysis and multiple regression analysis. The DEA technique is graphically illustrated for only two inputs and one output.…
