The Bayes factor is a ratio of two competing statistical models represented by their evidence, and is used to quantify the support for one model over the other. [1] The models in question can have a common set of parameters, such as a null hypothesis and an alternative, but this is not necessary; for instance, it could also be a non-linear model compared to its linear approximation.
This special case is how expected value of perfect information and expected value of sample information are calculated where risk neutrality is implicitly assumed. For cases where the decision-maker is risk averse or risk seeking , this simple calculation does not necessarily yield the correct result, and iterative calculation is the only way ...
As the data can be viewed as an evidence that support the estimated parameters, this process can be interpreted as "support from independent evidence adds", and the log-likelihood is the "weight of evidence".
There are a number of credit scoring techniques such as hazard rate modeling, reduced form credit models, the weight of evidence models, linear or logistic regression. The primary differences involve the assumptions required about the explanatory variables and the ability to model continuous versus binary outcomes.
The standard is met if the proposition is more likely to be true than not true. Another high-level way of interpreting that is that the plaintiff's case (evidence) be 51% likely. A more precise statement is that "the weight [of the evidence, including in calculating such a percentage] is determined not by the amount of evidence, but by its ...

If we knew f, then we could find the information lost from using g 1 to represent f by calculating the Kullback–Leibler divergence, D KL (f ‖ g 1); similarly, the information lost from using g 2 to represent f could be found by calculating D KL (f ‖ g 2). We would then, generally, choose the candidate model that minimized the information ...
