Ambiguity in measurement

Scientometrics, 1997
This paper gives an overview of the role of ambiguity in measurement and explores analytical methods for exploring its impact. It is argued that certain functional forms are more resilient than others to problems of ambiguity, and that these should be preferred when ambiguity is a serious concern.

Measuring ambiguity in the evidence theory

IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2006
In the framework of evidence theory, ambiguity is a general term proposed by Klir and Yuan in 1995 to gather the two types of uncertainty coexisting in this theory: discord and nonspecificity. Respecting the five requirements of total measures of uncertainty in the evidence theory, different ways have been proposed to quantify the total uncertainty, i ...

Data association with ambiguous measurements

2008 American Control Conference, 2008
We address the problem of tracking a single object in the neighborhood of several other closely spaced, similar objects where the sensor used to do the tracking may randomly measure the wrong object. Unlike many tracking scenarios, there is no other environmental clutter producing additional erroneous measurements.

On a measure of ambiguity

International Journal of Intelligent Systems, 1995
We consider a general characterization of a measure of ambiguity suggested by Fishburn and investigate the appropriateness of this characterization. It is shown that a number of concepts related to uncertainty and taken from fuzzy logic-measures of fuzziness, measures of specificity, and measures of possibility/certainty interval-satisfy this ...

Measurement of Ambiguity Tolerance

Journal of Personality Assessment, 1975
Presented definitions for the construct of ambiguity tolerance. The measure of ambiguity tolerance (MAT-50) had high internal reliability (r = .88) and high test-retest reliability (r = .86) over a 10-to-12 week period. A content analysis of the measure and a subjective analysis by 20 graduate students indicated adequate content validity.

Ambiguity Measurement [PDF]

, 2012
Ordering alternatives by their degree of ambiguity is a crucial element in decision processes in general and in asset pricing in particular. So far the literature has not provided an applicable measure of ambiguity allowing for such ordering. The current

A global measure of ambiguity for classification

1994
This paper suggests a a global measure of ambiguity based on the notion of an interval structure which can be viewed as a qualitative measure of belief. It is shown that the boundary region in the roughset model is a special case of the proposed measure.

A Note on Ambiguity in Portfolio Performance Measures

The Journal of Finance, 1980
IN A RECENT ARTICLE in the Journal of Finance [4], Richard Roll argues that the Security Market Line (SML) criterion gives ambiguous performance signals for portfolio evaluation. This note reports results of an empirical test of robustness of the SML criterion applied. to different indices over two time periods.

Implications of ambiguity for scientometric measurement

Journal of the American Society for Information Science and Technology, 2000
The essence of Scientometrics is precise measurement. Yet the measurements made in Scientometric research is steeped in ambiguity. This article explores the nature of ambiguity in measurement, and probes for mechanisms that allow regularities to be discovered in an environment in which ambiguity is pronounced.
