BACKGROUND Currently, most hospitals in the United States are obliged to report infections that occur following total joint arthroplasty to the Centers for Disease Control and Prevention through the National Healthcare Safety Network surveillance. The objective of this study was to identify the risk factors of surgical site infections that were reported to the Centers for Disease Control and Pr...

Although optimal cladograms based on real data sets are readily demonstrated to be well loaded with phylogenetic data, statistical means of evaluating dependability of details of branch arrangements have been problematic. Exact values of four measures of branch arrangement reliability nonparametric bootstrap and jackknife proportions, the Decay Index, and Bayesian posterior probabilities were o...

Left truncation and right censoring arise naturally in lifetime data. Left truncation arises because in many situations, failure of a unit is observed only if it fails after a certain period. Often, the units under study may not be followed until all of them fail and the experimenter may have to stop at a certain time when some of the units may still be working. This introduces right censoring ...

Because of the growing interest in nutraceuticals and their health benefits, it is important to develop tools for modeling degradation of nutraceuticals in low-moistureand high-temperature-heated foods. The objective of this study was to estimate the kinetic parameters for the degradation of anthocyanins in grape pomace and to calculate the bootstrap confidence interval (CI), which is a more re...

Copula as an effective way of modeling dependence has become more or less a standard tool in risk management, and a wide range of applications of copula models appear in the literature of economics, econometrics, insurance, finance, etc. How to estimate and test a copula plays an important role in practice, and both parametric and nonparametric methods have been studied in the literature. In th...

Abstract The maximum likelihood estimation of the parameters inverse Topp-Leone distribution under Type-II Censored Sample is studied, pivot value parameter constructed, accurate confidence interval and rejection region hypothesis test are obtained, statistical analysis carried out by numerical simulation.
