A fundamental issue that arises after fitting a regression model is that of testing the goodness of the fit. Our work brings together the power divergence family of goodness of fit tests and regression models for categorical time series. We show that under some reasonable assumptions, the asymptotic distribution of the power divergence family of goodness of fit tests converges to a normal rando...

The present article aims to examine Isaiah Berlin's views and ideas, and gives answers to the questions of how political goodness is linked to the concept of negative liberty in Berlin's thought,  and how his view of political goodness has formed his critique looking toward the political system of the Soviet Union. Political goodness in Berlin's thought seems to be multiplied, and from the plur...

Two studies considered the interplay between user-perceived usability (i.e., pragmatic attributes), hedonic attributes (e.g., stimulation, identification), goodness (i.e., satisfaction), and beauty of 4 different MP3-player skins. As long as beauty and goodness stress the subjective valuation of a product, both were related to each other. However, the nature of goodness and beauty was found to ...

This paper develops an approach to testing the adequacy of both classical and Bayesian models given sample data. An important feature of the approach is that we are able to test the practical scientiic hypothesis of whether the true underlying model is close to some hypothesized model. The notion of closeness is based on measurement precision and requires the introduction of a metric for which ...

Some assert that it is impossible to test preference restrictions against revealed preference. The “goodness” preference restriction simply assumes that one value of a nonmarket good is preferred over another other with any fixed commodity consumption. This paper uses a preference-theoretic methodology to show how goodness can be falsified by revealed preference for compensation-based welfare a...

The influence of sample size on informetric characteristics is examined to determine whether theoretical mathematical models can adequately fit large data sets. Two large data sets of queries submitted to the Excite search service were sampled for search characteristics (term frequencies, terms used per query, pages viewed per query, queries submitted per session) producing data sets of various...

In any environment of multiple information sources it is practically unavoidable that information sources would overlap; that is, describe the same portion of the real world. And when information sources overlap, it is practically unavoidable that information would be inconsistent; that is, describe diierently the same portion of the real world. In this report we deene a formal framework for re...
