Confidence & Credible Interval Estimates
Point estimates of unknown parameters θ governing the distribution of an observed quantity X are unsatisfying if they come with no measure of accuracy or precision. One approach to giving such a measure is to offer interval estimates for θ, rather than point estimates; upon observing X, we construct an interval [a, b] which is very likely to contain θ, and which is very short. The approach to e...
متن کاملOverconfidence in interval estimates.
Judges were asked to make numerical estimates (e.g., "In what year was the first flight of a hot air balloon?"). Judges provided high and low estimates such that they were X% sure that the correct answer lay between them. They exhibited substantial overconfidence: The correct answer fell inside their intervals much less than X% of the time. This contrasts with choices between 2 possible answers...

We propose an algorithm for calculating interval estimates for download times, based on an imprecise version of the linear regression algorithm and a discounted imprecise
متن کاملInterval Estimates When No Failures Are Observed
In this paper we discuss ways to use Bayesian methodology to estimate the matching performance of a biometric identification device when no errors are detected. One of the drawbacks to the classical or frequentist statistical estimation methods is that it is not possible to create a confidence interval for the error rate when no errors are observed. In this paper we begin by discussing the rele...
متن کاملCartesian Displays of Many Interval Estimates
We consider the problem of constructing static graphical representations of a large number of interval estimates. Because of clutter, traditional graphical summaries are visually ineffective for representing more then a few intervals. The Cartesian displays introduced in this article overcome the limitations stemming from visual clutter and can represent effectively very many intervals. The con...
