Energy use pattern and optimization of energy required for broiler production using data envelopment analysis
TL;DR: In this article, the authors used the nonparametric method of data envelopment analysis (DEA) to analyze energy efficiency, separate efficient from inefficient broiler producers, and calculate wasteful use of energy to optimize energy.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.

Measuring the efficiency of decision making units
TL;DR: A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs and methods for objectively determining weights by reference to the observational data for the multiple outputs and multiple inputs that characterize such programs.

Some Models for Estimating Technical and Scale Inefficiencies in Data Envelopment Analysis
TL;DR: The CCR ratio form introduced by Charnes, Cooper and Rhodes, as part of their Data Envelopment Analysis approach, comprehends both technical and scale inefficiencies via the optimal value of the ratio form, as obtained directly from the data without requiring a priori specification of weights and/or explicit delineation of assumed functional forms of relations between inputs and outputs as mentioned in this paper.

Data Envelopment Analysis: A Comprehensive Text with Models, Applications, References and DEA-Solver Software
TL;DR: In this article, the basic CCR model and DEA models with restricted multipliers are discussed. But they do not consider the effect of non-discretionary and categorical variables.

Carbon emission from farm operations
TL;DR: The available information on energy use in farm operations, and its conversion into carbon equivalent (CE) is a synthesis of the available information and shows that an output/input ratio, expressed either as gross or net output of C, must be >1 and has an increasing trend over time.
