background: the diagnosis of pulmonary tuberculosis (ptb) is complicated and time-consuming currently. there was association of ptb with serum tumor markers. in this study we aimed to evaluate the predictive role of serum ca125, ca199 and cea as diagnostic tools for ptb. methods: this study was designed as a case-control study with 565 subjects who visited the yijishan hospital from jun to dec ...

background: metabolic syndrome (metsy), an important predisposing factor for the most of noncommunicable diseases, has become a global pandemic. given different definitions used for the metsy, recently using a score termed “continuous metsy risk score (cmetsys)” is recommended. the aim of this study was to provide a cmetsys in a population-based sample of iranian adults and to assess its determ...

Photomultiplier tube (PMT) receiver is a promising solution for long-distance underwater wireless optical communication (UWOC) due to its characteristics of high gain, low noise, and large area. However, the complex environment leads dynamic change received intensity impacts stability reliability UWOC system using PMT. In this work, bandwidth limitation performance degradation caused by PMT sat...

In "Assessing the Belief Bias Effect With ROCs: It's a Response Bias Effect," Dube, Rotello, and Heit (2010) examined the form of receiver operating characteristic (ROC) curves for reasoning and the effects of belief bias on measurement indices that differ in whether they imply a curved or linear ROC function. We concluded that the ROC data are in fact curved and that analyses using statistics ...

We reassess the predictability of U.S. recessions at horizons from three months to two years ahead for a large number of previously proposed leading-indicator variables. We employ an efficient probit estimator for partially missing data and assess relative model performance based on the receiver operating characteristic (ROC) curve. While the Treasury term spread has the highest predictive powe...

Independent component analysis (ICA) has been successfully employed to decompose functional MRI (fMRI) time-series into sets of activation maps and associated time-courses. Several ICA algorithms have been proposed in the neural network literature. Applied to fMRI, these algorithms might lead to different spatial or temporal readouts of brain activation. We compared the two ICA algorithms that ...

Recently, the argument has been made that receiver operating characteristic (ROC) analysis should be used to compare the diagnostic performance of different lineup procedures. However, a drawback to ROC analysis is that is requires multiple correct and false ID rates for each lineup procedure being compared. When only a single pair of correct and false ID rates is measured, what dependent measu...
