Measuring economic efficiency using inverse-optimum weights

Measuring Economic Efficiency of Kidney Bean Production using Non-Discretionary Data Envelopment Analysis

Efficient use of assets in agriculture is a goal for policy-makers and farmers. Agricultural input resources are scarce therefore optimum use of inputs in different agricultural operations is important. Mathematical programming technique such as data envelopment analysis (DEA) is a well-known approach for estimation efficiency of agricultural DMUs. In this study, efficiency of kidney bean produ...

measuring efficiency using fuzzy dea and fuzzy constraints to control weights and to find a common set of weights

in this paper it has been tried to present a model by usingsome changes in the classical dea models and combining these modelswith fuzzy models to eliminate these weaknesses. inputs and outputs arerecognized by using mcdm and ahp techniques and experts views. inthe next step, the gathered data is compounded by fuzzy techniques andentered in the special dea model after changing to the crisp amou...

Median regression using inverse censoring weights

We implement semiparametric random censorship model aided inference for censored median regression models. This is based on the idea that, when the censoring is specified by a common distribution, a semiparametric survival function estimator acts as an improved weight in the so-called inverse censoring weighted estimating function. We show that the proposed method will always produce estimates ...

Measuring Interval Efficiency in Convex Hull of Data Using DEA

Measuring cardiac efficiency using PET/MRI.

Lawrence Berkeley National Laboratory, USA Heart failure (HF) is a complex syndrome that is projected by the American Heart Association to cost $160 billion by 2030. In HF, significant metabolic changes and structural remodeling lead to reduced cardiac efficiency. A normal heart is approximately 20-25% efficient measured by the ratio of work to oxygen utilization (1 ml oxygen = 21 joules). The ...
