SUMMARY Comparison of the accuracy of two diagnostic tests using the receiver operating characteristic (ROC) curves from two diagnostic tests has been typically conducted using fixed sample designs. On the other hand, the human experimentation inherent in a comparison of diagnostic modalities argues for periodic monitoring of the accruing data to address many issues related to the ethics and ef...

Electricity generation in thermal power plants as the largest producer of electricity in Iran is associated with greenhouse gas emissions. In this paper, using the Malmquist-Luenberger method, green productivity, and efficiency changes are measured for 31 thermal power plants (including 12 steam power plants, 13 gas power plants, and six combined cycle power plants) during 2009-2016. The result...

Bootstrap resampling techniques, introduced by Efron and Rubin, can be presented in a general Bayesian framework, approximating the statistical distribution of functional ?(F), where F is random function. Efron’s Rubin’s bootstrap procedures extended, introducing an informative prior through Proper bootstrap. In this paper different techniques are used compared predictive classification regress...

Over the last few decades, public programs have driven gradual adoption of information and communication technologies (ICTs) in education. The most ambitious project Spain so far was Escuela 2.0, which provided students from regions that opted into program with laptops. objective this paper is to evaluate impact on school performance productivity. To do this, we developed a new methodological a...

Recent biomedical studies often measure two distinct sets of risk factors: low-dimensional clinical and environmental measurements, and high-dimensional gene expression measurements. For prognosis studies with right censored response variables, we propose a semiparametric regression model whose covariate effects have two parts: a nonparametric part for low-dimensional covariates, and a parametr...
