A recently derived function ties a portfolio’s loss given default rate (LGD) to its default rate. This study compares the predictive performance of the LGD function to that of linear regression using simulated data. The data are simulated using a linear model. Even though this confers an advantage to linear regression, the LGD function produces lower mean squared error over a meaningful range o...

Existing research on category-based induction has primarily focused on reasoning about blank properties, or predicates that are designed to elicit little prior knowledge. Here, we address reasoning about nonblank properties. We introduce a model of conditional probability that assumes that the conclusion prior probability is revised to the extent warranted by the evidence in the premise. The de...

Lippe rejected out of hand the idea advanced by Morris [5] that pain was a pluralistic concept. Rather, he asserted “the biomedical basis of maldynia.” In Lippe’s medicocentric view of pain, “maldynia” was neither a symptom nor a syndrome but an “illness with endogenous and exogenous components.” Thus defined, “eudynia” becomes a teleologically beneficial mechanism, whereas “maldynia” is “usele...

We express Brewka’s prioritised default logic (PDL) as argumentation using ASPIC. By representing PDL as argumentation and designing an argument preference relation that takes the argument structure into account, we prove that the conclusions of the justified arguments correspond to the PDL extensions. We will first assume that the default priority is total, and then generalise to the case wher...
