Data envelopment analysis (DEA) is a non-parametric approach to evaluate a set of decision making units (DMUs) consuming multiple inputs to produce multiple outputs. Formally, DEA use to estimate the efficiency score into the empirical efficient frontier. Also, DEA can be used to allocate resources and set targets for future forecast. The data are continuous in the standard DEA model whereas th...
We give a novel algorithm for finding a parsimonious context tree (PCT) that best fits a given data set. PCTs extend traditional context trees by allowing context-specific grouping of the states of a context variable, also enabling skipping the variable. However, they gain statistical efficiency at the cost of computational efficiency, as the search space of PCTs is of tremendous size. We propo...
This paper describes the efficiency of Dutch hospitals using the method of Data Envelopment Analysis (DEA). In particular the analysis focuses on explaining cost inefficiency measures due to each hospital's operating environment. In previous works, the resulting DEA score is regressed on environmental factors via a Tobit approach. Previously, these approaches have been used (Simar and Wilson, J...
Introduction: Evaluation is an important factor in productivity context, and acts as a control system for other areas of productivity. Hospitals are large organizations incurring heavy expenses in every country. The level of efficiency in a hospital is a good criterion to understand how hospitals consume their resources. The goal of this research was to determine relative efficiency of 13 publi...
OBJECTIVES To compare the discriminative power of the five-level version of the EuroQol five-dimensional questionnaire (EQ-5D-5L [5L]) and its three-level version (EQ-5D-3L [3L]) in patients with diabetes in Singapore. METHODS A consecutive sample of patients with type 2 diabetes mellitus (T2DM) self-completed the two versions of the EQ-5D in the clinic. The 3L index score was calculated from...
Introduction: Identification and promotion of diagnostic methods has been a continuous effort to reduce disease and its complications and reduce costs associated with treatment. Despite all these efforts and improving our knowledge of diseases and diagnostic tools, pediatric appendicitis remains part of the diagnostic challenge in the surgical field. The aim of this is to compare the two diagno...
data envelopment analysis (dea) is a technique based on mathematical programming for evaluating the efficiency of homogeneous decision making units (dmus). in this technique, inefficient dmus are projected onto the frontier, which was constructed by the best performers. centralized resource allocation (cra) is a method in which all dmus are projected onto the efficient frontier through solving ...
in this study, the aim was to determine whether adding vitamin d to the standard therapeutic regimen of schizophrenic male patients with inadequate vitamin d status could improve some aspects of the symptom burden or not. this study was an open parallel label randomized clinical trial. eighty patients with chronic stable schizophrenia with residual symptoms and vitamin d deficiency were recruit...
cumulative embryo score (ces) is one of the many embryo scoring methods which have been developed to help clinicians to transfer high quality embryos and predict pregnancy rate in assisted reproductive techniques (art) cycles. regarding the existing difference in ces calculation this study was done to compare two methods in order to determine the more practical and preferable one. in a retrospe...
BACKGROUND Identification of the risk of recurrent falls is complex in older adults. The aim of this study was to examine the efficiency of 3 artificial neural networks (ANNs: multilayer perceptron [MLP], modified MLP, and neuroevolution of augmenting topologies [NEAT]) for the classification of recurrent fallers and nonrecurrent fallers using a set of clinical characteristics corresponding to ...
