Misalignment Between Research Hypotheses and Statistical Hypotheses: A Threat to Evidence-Based Medicine?

TESTING STATISTICAL HYPOTHESES UNDER FUZZY DATA AND BASED ON A NEW SIGNED DISTANCE

This paper deals with the problem of testing statisticalhypotheses when the available data are fuzzy. In this approach, wefirst obtain a fuzzy test statistic based on fuzzy data, and then,based on a new signed distance between fuzzy numbers, we introducea new decision rule to accept/reject the hypothesis of interest.The proposed approach is investigated for two cases: the casewithout nuisance p...

Similarity between hypotheses and evidence.

We explore two novel consequences of similarity-based likelihood judgment. In Section I, we distinguish between the evidence on which judgments are based and the hypotheses that serve as the objects of judgment. The location of a feature, whether in the evidence or the hypotheses, influences the perceived similarity between evidence and hypotheses and consequently yields judgments that are inco...

THE ASSOCIATION BETWEEN FATTY LIVER and sudden death has long been suspected, particularly in forensic pathology, but its pathogenic mechanisms remain elusive. This report describes several cases of fatty liverassociated sudden death in connection with extensive right ventricular fatty replacement. On the basis of the findings described in this study, it is hypothesized that extensive fatty rep...

OBJECTIVE: To establish an experimental model of extracorporeally perfused non-pregnant swine uteri for the study of uterine contractility, peristalsis and transport mechanisms through the female genital tract using an intrauterine double-chip microcatheter. In order to validate the model described biochemical parameters were assessed during the whole perfusion time. METHODS: An extracorporeal ...
