Drawing inferences about treatment effects is of interest in many fields. We consider Robins’s marginal and nested structural models and propose likelihood and regression estimators in the cross-sectional setting. First, we choose to retain a finite subset of all inherent and modelling constraints on the the joint distributions of potential outcomes and covariates under a correctly specified pr...
This study examines the technical efficiency of the electricity generation companies in a deregulated electricity market. Two approaches are used – parametric and non-parametric. Parametric models show that there exist high levels of efficiency among the generation firms; the lowest score is 99.83%, after accounting for noise. While non-parametric models do not give efficiency scores as high as...
in the present study an attempt has been made to use a non-parametric method data envelopment analysis (dea) for assessing source-wise and operation-wise the technical efficiency (te) and return-to-scale (rts) for paddy production in four zones of the state of punjab, india. the results were then compared to corresponding ones already obtained from a parametric method (cobb-douglas production f...
Background: The implementation effect of nurses' efficiency improvement law on their job satisfaction is still not clear. Therefore, the aim of this study was to investigate nurses' job satisfaction after execution of the efficiency improvement law among them. Methods: This analytic study was carried out among 410 clinical nurses selected through a convenient and accessible sampling method and...
Data envelopment analysis (DEA) is a method for estimating efficiency of decision making units (DMU).The method done by means of weighted output to input ratio with the weights being optimal virtual prices of such activities for all units. Cross efficiency evaluation has long been proposed as an alternative method for ranking DMUs. The major problem that reduced the usefulness of cross efficien...
Using a multistudy approach, we examined the utility of the Impairment Rating Scale (IRS; Fabiano et al., 2006) as a screening tool for detecting kindergarten children who are at risk for social, emotional, academic, and behavioral problems. In Study 1 (N = 568), we evaluated the concurrent validity, discriminant validity, and diagnostic efficiency of the parent and teacher IRS test score infer...
OBJECTIVE To develop a composite indicator to evaluate the quality of municipal management of primary health care. METHODS The evaluation model focuses on aspects of health system management. Fifty-five performance indicators were used and classified according to the criteria of relevance, effectiveness, efficacy and efficiency. The measures were aggregated through an additive data envelopmen...
Emerging technologies are playing an important role in establishing competitive advantage for technology based companies. Selecting an efficient and important emerging technology to invest in is significant to the companies also. In this study, we propose a method for selecting optimal emerging technology which is efficient, important and the most suitable to a company’s actual levels of input ...
Introduction: Nowadays there is more inclination for using computer-based education for teenagers. With regard to the limited number of studies on the efficiency of these methods toward puberty hygiene education, this study aims to determine the effect of software on knowledge and performance of teenage girls toward puberty hygiene. Methods: This trial was carried out on 620 teenage girls who ...
