We propose an incentive pay scheme for educators that links educator compensation to the ranks of their students within appropriately defined comparison sets. Because this scheme employs only ordinal information, it allows education authorities to employ new assessments at each testing date without ever having to equate various assessment forms. Thus, our scheme mitigates incentives for teacher...

Four algorithms for percentile filtering are compared. The ways they can be implemented in hardware and software, their flexibility and their speed are taken into account.

The purpose of this study is to find the percentiles of fuzzy numbersand to demonstrate their applications, which include finding weightedmeans, dispersion indices, and the percentile intervals of fuzzy numbers. Thecrisp approximations of fuzzy numbers introduced in this paper are new andinteresting for the comparison of fuzzy environments, such as a variety of economic,financial, and engineeri...

In this paper, we propose five prediction intervals for the beta autoregressive moving average model. This model is suitable modeling and forecasting variables that assume values in interval $(0,1)$. Two of proposed are based on approximations considering normal distribution quantile function distribution. We also consider bootstrap-based intervals, namely: (i) bootstrap errors (BPE) interval; ...

OBJECTIVE We aimed to determine the ideal cut-off of nadir serum CA-125 level for prediction of progression free survival. METHODS Among 267 patients who achieved complete remission after chemotherapy, the correlation between nadir CA-125 and progression free survival were compared among the subgroups classified according to the distribution of CA-125. The diagnostic odds ratio and area under...

OBJECTIVE We hypothesized that childhood obesity would be associated with decreased likelihood of survival to hospital discharge after in-hospital, pediatric cardiopulmonary resuscitation (CPR). METHODS We reviewed 1477 consecutive, pediatric, CPR index events (defined as the first CPR event during a hospitalization in that facility for a patient <18 years of age) reported to the American Hea...

Background—An imbalance in circulating angiogenic factors plays a central role in the pathogenesis of preeclampsia. Methods and Results—We prospectively studied 616 women who were evaluated for suspected preeclampsia. We measured plasma levels of antiangiogenic soluble fms-like tyrosine kinase 1 (sFlt1) and proangiogenic placental growth factor (PlGF) at presentation and examined for an associa...
