Testing of hypotheses

This is a survey of nonlinear regression models, with an emphasis on the theory of estimation and hypothesis testing rather than computation and applications, although there will be some discussion of the last two topics. For a general discussion of computation the reader is referred to Chapter 12 of this Handbook by Quandt. My aim is to present the gist of major results; therefore, I will sometimes omit proofs and less significant assumptions. For those, the reader must consult the original sources....

Research is an activity which people undertake in order to find things in a systematic way as a means of increasing their knowledge base. Dissertations must follow Graduate School guidelines, whereas criteria for style and organization of a research paper are at the discretion of the professor.

We describe a corpusbased investigation of proposals in dialogue. First, we describe our DR/compliant coding scheme and report our intercoder reliability results. Next, we test several hypotheses about what constitutes a wellformed proposal. 1 Introduction we report our findings .on tracking agreement. 2 Tracking Agreement Our corpus consists of 24 computermediated dialogues 1 in which two participants collaborate on a simple task of buying furniture for the living and dining rooms of a house (a variant of the task in (Walker, 1993)). ...

We test three hypotheses concerning the impact of loan market competition on euro area banks’ loan and deposit rates. First, we examine the effect of loan market competition on the level on bank loan and deposit rates; second, using a panel errorcorrection model (ECM) we estimate the effect of loan market competition on the longrun equilibrium passthrough of bank interest rates to changes in corresponding market interest rates; third, we also test the impact of competition in the loan market on the immediate adjustment of bank interest rates to changes in market interest rates....

We investigate the connection between part of speech (POS) distribution and content in language. We deﬁne POS blocks to be groups of parts of speech. We hypothesise that there exists a directly proportional relation between the frequency of POS blocks and their content salience. We also hypothesise that the class membership of the parts of speech within such blocks reﬂects the content load of the blocks, on the basis that open class parts of speech are more contentbearing than closed class parts of speech.

The last twenty years of the last millennium are characterized by complex automatization of industrial plants. Complex automatization of industrial plants means a switch to factories, automatons, robots and self adaptive optimization systems. The mentioned processes can be intensified by introducing mathematical methods into all physical and chemical processes

Overall, our analysis can be understood as one of the first crosscountry empirical studies on the determinants of bank fees and as a contribution to the literature testing the contradictory empirical predictions of the SCP and ES hypotheses regarding the influence of concentration on prices in the banking industry.

Because larger ﬁrms are much more likely to be covered by collective bargaining contracts and works councils, a closely related issue concerns the independent role of ﬁrm size in providing wage insurance. As ﬁrm size is typically viewed as a good proxy for capital market access (e.g., Gertler and Gilchrist 1994), insurance contracts should be particularly apparent for individuals working at larger employers.

As science, ecology is often accused of being weak because of its basic lack of predictive power (Peters 1991) and the many ecological concepts judged vague or tautological (ShraderFrechette and McCoy 1993). Also, important paradigms that dominated the ecological scene for years have been discarded in favor of new concepts and theories that swamp the most recent ecological literature (e.g., the abandoning of the island biogeography theory in favor of the metapopulations theory; Hanski and Simberloff 1997).

This paper suggests refinements for the Distributional Similarity Hypothesis. Our proposed hypotheses relate the distributional behavior of pairs of words to lexical entailment – a tighter notion of semantic similarity that is required by many NLP applications. To automatically explore the validity of the defined hypotheses we developed an inclusion testing algorithm for characteristic features of two words, which incorporates corpus and webbased feature sampling to overcome data sparseness. ...

A number of results in the study of realtime sentence comprehension have been explained by computational models as resulting from the rational use of probabilistic linguistic information. Many times, these hypotheses have been tested in reading by linking predictions about relative word difﬁculty to wordaggregated eye tracking measures such as gopast time. In this paper, we extend these results by asking to what extent reading is wellmodeled as rational behavior at a ﬁner level of analysis, predicting not aggregate measures, but the duration and location of each ﬁxation. ...

In panel data models (as in singleequation multipleregression models) we are interested in testing two types of hypotheses: hypotheses about the variances and covariances of the stochastic error terms and hypotheses about the regression coefficients. The general to simple procedure provides a good guide.
