Confidence Intervals for Reliability 1 Running head: CONFIDENCE INTERVALS FOR RELIABILITY COEFFICIENTS Estimation of and Confidence Interval Formation for Reliability Coefficients of Homogeneous Measurement Instruments
The reliability of a composite score is a fundamental and important topic in psychology and related disciplines. The most commonly used reliability estimate of a composite score is coefficient alpha. However, under regularity conditions, the population value of coefficient alpha is only a lower bound on the population reliability, unless the items are essentially tau-equivalent, an assumption t...
متن کاملSample size planning for composite reliability coefficients: accuracy in parameter estimation via narrow confidence intervals.
Composite measures play an important role in psychology and related disciplines. Composite measures almost always have error. Correspondingly, it is important to understand the reliability of the scores from any particular composite measure. However, the point estimates of the reliability of composite measures are fallible and thus all such point estimates should be accompanied by a confidence ...
متن کاملConfidence Intervals for Lower Quantiles Based on Two-Sample Scheme
In this paper, a new two-sampling scheme is proposed to construct appropriate confidence intervals for the lower population quantiles. The confidence intervals are determined in the parametric and nonparametric set up and the optimality problem is discussed in each case. Finally, the proposed procedure is illustrated via a real data set.

متن کاملLarge-Sample and Deterministic Confidence Intervals for Online Aggregation
The online aggregation system recently proposed by Hellerstein, et al. permits interactive exploration of large, complex datasets stored in relational database management systems. Running confidence intervals are an important component of an online aggregation system and indicate to the user the estimated proximity of each running aggregate to the corresponding final result. Large-sample confid...
