The weights of evidence, a quantitative method for combining evidence in support of a hypothesis, is commonly used in pattern based models. It enables mapping the probability of the occurrence of a certain event such as, for example, a land cover change, a wildfire or a landslide using a map of the occurence of this event and ancillary data.

Optimal weights of evidence with bounded influence
Metrika, 2002A fundamental statistical problem is to indicate which of two hypotheses is better supported by the data. Statistics designed for this purpose are called weight of evidence. In this paper we study the problem of robust weights of evidence, optimal in their performance while robust in the infinitesimal sense of the influence function.

Asymptotics of guarded weights of evidence
Journal of Statistical Planning and Inference, 2000Abstract A test at a significance level α yields a decision which can be quantified by assigning the value 1 if the null hypothesis is rejected and 0 otherwise. The theory of guarded weights of evidence for the alternative (Blyth and Staudte, 1995. Statist. Probab. Lett.

Carcinogenicity of Chemicals: The Weight of Evidence
Human Toxicology, 1988. The evidence discussed here is derived from epidemiology, long-term bioassays in laboratory animals, and predictive short-term tests. Epidemiological data are obtained directly from human studies and are most compelling when hey demonstrate a large relative risk and a clear dose-response in association with a distinctive umour type.

Weighing the Evidence: Benefits of Regular Weight Monitoring for Weight Control
Journal of Nutrition Education and Behavior, 2005We address the assertion that weighing obese patients in weight loss programs can be a source of distress and can lead to unfavorable outcomes. Examination of the relevant literature suggests that there is no evidence that weighing by weight loss participants is a cause of negative mood or of body dissatisfaction. Further, there is little evidence that

Perceptual Accuracy in the Balance: The Weight of the Evidence and the Evidence of Weight
Journal of Social and Personal Relationships, 1998In two studies, we investigated whether individuals were accurate in perceiving weight-related attitudes of their romantic partner. We also investigated whether accuracy was moderated by whether the partner was currently attempting to lose weight, relationship commitment level, amount of discussion about weight and importance of weight.

You have undoubtedly heard a good deal about global warming. But if you’re like most Americans, you feel somewhat confused about the topic. According to a national survey in 2010, only one in every 10 Americans feels very well informed about the causes of global warming and how Earth’s climate system works.

Weight of Evidence: Criteria and Applications
Toxicologists and authorities evaluate substances that in the traditional way refer to data and knowledge on the toxic mechanism. Non-testing methods (NTMs) proved to be a valuable resource for risk assessment of chemical substances. Indeed, they can be particularly useful when the information provided by different sources is integrated to increase ...Erika, Colombo +3 more

In this chapter, I explicate the weight of evidence account. The weight of evidence accorded a hypothesis is highly dependent on the accuracy of the evidence, which is understood to mean a combination of validity and precision. Validity is concerned with biases and confounding, which can distort the measure of effect, whereas precision is often ...

Youden's Index and the Weight of Evidence
Methods of Information in Medicine, 2015SummaryBy means of Shannon’s relationship between information and probability, Youden’s index for rating diagnostic tests is shown to be a probability-scale analogue of the log-likelihood ratio of a positive test outcome.
