Simple improved con dence intervals for comparing matched proportions 3
نویسنده
چکیده
For binary matched-pairs data, this article discusses interval estimation of the di erence of probabilities 7 and an odds ratio for comparing ‘success’ probabilities. We present simple improvements of the commonly used Wald con dence intervals for these parameters. The improvement of the interval for the 9 di erence of probabilities is to add two observations to each sample before applying it. The improvement for estimating an odds ratio transforms a con dence interval for a single proportion. Copyright ? 11 2004 John Wiley & Sons, Ltd.

Simultaneous Con®dence Intervals for the Difference of Two Survival Functions
In comparing two treatments with failure time observations, con®dence bands for the `̀ difference'' of two survival curves provide useful information about a global picture of the treatment difference over time. In this note, we propose a rather simple procedure for constructing such simultaneous con®dence intervals. Our technique can also be used in the one-sample case, which has been extensive...
متن کاملExact Hypothesis Testing without Assumptions - New and Old Results not only for Experimental Game Theory1
This is an overview of tests for hypothesis testing that only rely on objective characteristics of the data generating process and do not rely on additional assumptions when making inference. In particular the methods are distribution-free, many apply to nonparametric settings. Only exact results are presented, results that can be proven for the given nite sample. Asymptotic theory is not used...
متن کاملImproved estimation, evaluation and applications of confidence measures for speech recognition
This paper describes our approach to the estimation of con dence in the words generated by a speech recognition system. We describe the models and the features employed for con dence estimation. In addition we discuss the characteristics of an information-theoretic metric for assessing the performance of the con dence measure. We provide a simple application of con dence measures in which we ra...
متن کاملSimultaneous Con dence Intervals for Linear Estimates of Linear Functionals
This note presents three ways of constructing simultaneous condence intervals for linear estimates of linear functionals in inverse problems, including \Backus-Gilbert" estimates. Simultaneous con dence intervals are needed to compare estimates, for example, to nd spatial variations in a distributed parameter. The notion of simultaneous con dence intervals is introduced using coin tossing as an...
متن کاملLikelihood Ratio Based Con dence Intervals in Survival Analysis
Con dence intervals for the survival function and the cumulative hazard function are considered. These con dence intervals are based on an inversion of the likelihood ratio statistic. To do this two extensions of the likelihood, each of which yields meaningful likelihood ratio hypothesis tests and subsequent con dence intervals, are considered. The choice of the best extension is di cult. In th...
