A Scale-Sensitive Test of Attraction and Repulsion Between Spatial Point Patterns

A Scale-sensitive Test of Attraction and Repulsion between Spatial Point Patterns∗

There exist a variety of tests for attraction and repulsion effects between spatial point populations, most notably those involving either nearest-neighbor or cell-count statistics. Diggle and Cox (1981) showed that for the nearestneighbor approach, a powerful test could be constructed using Kendall’s rank correlation coefficient. In the present paper, this approach is extended to cell-count st...

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

the relationship between eq, iq and test format: a study on test fairness

the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...

A Model of Lexical Attraction and Repulsion

This paper introduces new methods based on exponential families for modeling the correlations between words in text and speech. While previous work assumed the effects of word co-occurrence statistics to be constant over a window of several hundred words, we show that their influence is nonstationary on a much smaller time scale. Empirical data drawn from English and Japanese text, as well as c...
