Gaining confidence in the revised consumer confidence indicator: nonlinear optimization approach

Empirical Economics
This study aims to methodologically improve the European consumer confidence indicator (CCI), one of the most closely observed economic indicators. Our models utilize nonlinear optimization targeting to maximize the number of correctly predicted directions of change in the annual final consumption growth rates. We also opt for a new weighting scheme as

5. A Dual-Source Indicator of Consumer Confidence

Sociological Methodology, 1997
The objective of this paper is to improve the U.S. leading confidence indicator by combining its amended version with the Conference Board's equally well known Consumer Expectation Index. The resulting dual-source indicator provides a factorial structure in which survey items are nested.

Reliability Confidence Indicator

2020 Annual Reliability and Maintainability Symposium (RAMS), 2020
The capability of a product to meet the expected reliability targets is extremely difficult to measure during the product development phases. Unlike weight, power consumption, or any other physical or performance parameters, there are no standard defined means to measure the status of the reliability during the various phases of the product development.

Confidence Bounds for Capability Indices

Journal of Quality Technology, 1992
Capability indices compare the actual performance of a manufacturing process to the desired performance. In practice these indices are estimated using sample data, often with quite small sample sizes. Thus, it is of interest to obtain confidence limits ..

Confidence intervals for the difference in paired Youden indices

Pharmaceutical Statistics, 2012
Comparison of accuracy between two diagnostic tests can be implemented by investigating the difference in paired Youden indices. However, few literature articles have discussed the inferences for the difference in paired Youden indices. In this paper, we propose an exact confidence interval for the difference in paired Youden indices based on the ...

Action Confidence as an Indicator of Transformative Change

Journal of Transformative Education, 2020
This article reports on the findings from an interview-based, qualitative study of adult learners in Scotland participating in the MITx u.lab massive open online course in 2015 and 2016. It focuses on interviewees’ accounts of the impact of participating in u.lab on their work and lives.

Generalized confidence intervals for process capability indices

Quality and Reliability Engineering International, 2006
AbstractThe concept of generalized confidence intervals is used to derive lower confidence limits for some of the commonly used process capability indices. For the cases where approximate lower confidence limits are already available, numerical comparisons are made among the available approximations and the generalized lower confidence limit.
