Piece-wise linear isotonic regression
Timo Kuosmanen, Juan F. Monge, José L. Ruiz +1
Isotonic regression provides a flexible, tuning-free approach to estimating monotonic functions without imposing global curvature constraints, yet the estimated regression function…
Benchmarking within a DEA framework: setting the closest targets and identifying peer groups with the most similar performances
José L. Ruiz, Inmaculada Sirvent
Data Envelopment Analysis (DEA) is widely used as a benchmarking tool for improving performance of organizations. For that purpose, DEA analyses provide information on both target…
Cross-benchmarking for performance evaluation: looking across best practices of different peer groups using DEA
Nuria Ramón, José L. Ruiz, Inmaculada Sirvent
In benchmarking, organizations look outward to examine others' performance in their industry or sector. Often, they can learn from the best practices of some of them and improve. I…
Performance evaluation through DEA benchmarking adjusted to goals
José L. Ruiz, Inmaculada Sirvent
Data Envelopment Analysis (DEA) is extended to the evaluation of performance of organizations within the framework of the implementation of plans for improvements that set manageme…
DEA-based benchmarking for performance evaluation in pay-for-performance incentive plans
Wade D. Cook, Nuria Ramón, José L. Ruiz +2
Incentive plans involve payments for performance relative to some set of goals. In this paper, we extend Data Envelopment Analysis (DEA) to the evaluation of performance in the spe…
Two-step benchmarking: Setting more realistically achievable targets in DEA
Nuria Ramón, José L. Ruiz, Inmaculada Sirvent
The models that set the closest targets have made an important contribution to DEA as tool for the best-practice benchmarking of decision making units (DMUs). These models may help…
Robust DEA efficiency scores: A probabilistic/combinatorial approach
Mercedes Landete, Juan F. Monge, José L. Ruiz
In this paper we propose robust efficiency scores for the scenario in which the specification of the inputs/outputs to be included in the DEA model is modelled with a probability d…
Sharpe portfolio using a cross-efficiency evaluation
Juan F. Monge, Mercedes Landete, José L. Ruiz
The Sharpe ratio is a way to compare the excess returns (over the risk free asset) of portfolios for each unit of volatility that is generated by a portfolio. In this paper we intr…
