Remark: Economist’s Heuristics for the Neyman-Pearson Lemma Cosma Shalizi of Carnegie Mellon has suggested the following nice heuristic argument for the optimality of likelihood ratio tests. We want to choose a rejection region, R such that under the alternative hypothesis, the probability of falling into R, which we will denote, Q(R) is as large as possible, given that we satisfy a constraint ...

INTRODUCTION The purpose of this in vitro study was to introduce a new method to describe root canal curvatures and to assess the degree of curvature of human permanent mandibular teeth with curved root canals. MATERIALS AND METHODS One hundred and thirty five mesial root canals of mandibular first and second molar teeth were selected. Access cavities were prepared. After inserting a K-file s...

Detecting dependence between two random variables is a fundamental problem. Although the Pearson correlation coefficient is effective for capturing linear dependence, it can be entirely powerless for detecting nonlinear and/or heteroscedastic patterns. We introduce a new measure, G-squared, to test whether two univariate random variables are independent and to measure the strength of their rela...

The article contains data pertaining to the reconstruction of an 8-lead ECG from 2 subcutaneous implantable cardioverter defibrillator vectors. The location of electrodes on the precordium required for the data collection are detailed; the flow chart for patient selection and exclusion is shown; the summary data of the root mean square error (RMSE) (in microvolts) and Pearson r for the ECG tran...

The aim of this investigation was to compare the degree of striatal dopamine-(D2) receptor blockade by two atypical antipsychotic drugs, risperidone and olanzapine. The percentage of D2 receptor occupancy during treatment was calculated by comparing the results of 123I-iodobenzamide SPECT with those from healthy control subjects. Twenty inpatients suffering from schizophrenia or schizoaffective...

conclusions based on the results, improving self-compassion and anger-control skills are suggested as ways to decrease suicide ideation. results the results of the pearson correlation coefficient tests showed that suicide ideation was negatively correlated with self-compassion (r = -0.19; p < 0.05) and mindfulness components (r = -0.20; p < 0.05), but it was positively correlated with self-judg...

This group began with an open brainstorming session intended to identify major political, economic and social issues raised by the information revolution that had not, in the view of participants, been sufficiently addressed in the conference plenary sessions. Such issues would be of concern to Europe but not exclusively so. Next the group focused its attention on information revolution questio...

OBJECTIVE The Disability of Arm, Shoulder and Hand (DASH) questionnaire is a tool for measuring physical function and symptoms of the upper extremity. Although widely used, it is not validated for rheumatoid arthritis (RA). In this study the DASH was validated for this patient group. METHODS In total, 102 patients participated in this study. For the validation, the questionnaires of the DASH,...

Giant bamboo Dendrocalamus asper is recommended in environmental and livelihood programs in the Philippines due to its various ecological, economic and social benefits. However, there are limited data on the ecology of giant bamboo litterfall production, which contributes to soil nutrient availability. Bamboo also contributed in carbon sequestration. The study was conducted within the ...
