Data‐driven hypotheses

Testing fuzzy hypotheses with vague data

The problem of testing fuzzy hypotheses in the presence of vague data is considered. A new method based on the necessity index of strict dominance (NSD) is suggested. An example hoe to apply the proposed test in statistical quality control is shown.

Medical Hypotheses

The possibility that patients with disorders that improve with administration of large, pharmacologic dosages of glucocorticoids, such as chronic allergies and autoimmune disorders, might have mild deficiency of cortisol production or utilization has received little attention. Yet evidence that patients with rheumatoid arthritis improved with small, physiologic dosages of cortisol or cortisone ...

The Relation between Abductive Hypotheses and Inductive Hypotheses

In the AI eld, abduction is used for design, diagnosis and other tasks. This is because abduction is a sort of predictive inference. On the other hand, induction is used for classiication. For example, ILP nds greater tendencies in examples and learns general rules from the examples and background knowledge. Recently, the integration of abduction and induction has become a hot issue. In this pa...

Expectations Hypotheses Tests

We investigate the expectations hypotheses of the term structure of interest rates and of the foreign exchange market using vector autoregressive methods for U.S. dollar, Deutsche mark, and British pound interest rates and exchange rates. We examine Wald, Lagrange multiplier, and distance metric tests by iterating on approximate solutions that require only matrix inversions. Bias-corrected, con...
