A graphical model is a graph that represents a set of conditional independence relations among the vertices (random variables). The graph is often given a causal interpretation as well. I describe how graphical causal models can be used in an algorithm for constructing partial information about...

Systemic realist arguments of foreign policy decision-making suggest that partisan disagreement stops at the water's edge. A domestic-politics model of foreign policy decision-making posits that politics does not stop at the water's edge. Extant research on foreign policy voting in the U.S....

The purpose of this research is to examine the issue of measurement context effects in survey-based tests of attitudinal and related models. The specific issue examined concerns the degree to which the measurement process affects the objects of measurement (i.e., various attitudinal and related...

Credit ratings issued by international agencies are extensively used in practice to support investment and financing decisions. Furthermore, a considerable portion of the financial research has been devoted to the analysis of credit ratings, in terms of their effectiveness, and practical...

This study introduces a simple nonparametric test for the relative discrimination of models in international relations research. The common parametric approach, the Vuong test, does not perform well under the small-n, high canonical correlation conditions that are sometimes encountered in world...

In this paper a real analysis approach to stock price modelling is considered. A stock price and its return are defined in a duality to each other provided there exist suitable limits along a sequence of nested partitions of a time interval, mimicking sum and product integrals. It extends the...

The authors propose six questions relevant to the evaluation of all social system models, and apply them to the Barr-Gale model for forecasting the Consumer Price Index for Food. While analysts invest much effort in developing new economic models, relatively little attention is paid to...
