Variance Estimation and Confidence Intervals for 11 Commonly Used Health Disparity Measures

Variance Estimation and Construction of Confidence Intervals for GEE Estimator

Generating Confidence in the SAS® System: Confidence Intervals for Commonly Used Procedures

Confidence intervals have recently been galnmg favor as the preferred manner of reporting statistical results in medical journals. Correspondingly. there has been a trend away from overreliance on probability (P) values. A P value informs the reader about the probability that the population parameter being estimated using sample data is nil. combining information on both the magnitude and the p...

Generalized Confidence Intervals and Fiducial Intervals for Some Epidemiological Measures

For binary outcome data from epidemiological studies, this article investigates the interval estimation of several measures of interest in the absence or presence of categorical covariates. When covariates are present, the logistic regression model as well as the log-binomial model are investigated. The measures considered include the common odds ratio (OR) from several studies, the number need...

Lecture 11: Confidence intervals and model comparison for linear regression; analysis of variance

Just as there was a close connection between hypothesis testing with the one-sample t-test and a confidence interval for the mean of a sample, there is a close connection between hypothesis testing and confidence intervals for the parameters of a linear model. We’ll start by explaining the confidence interval as the fundamental idea, and see how this leads to hypothesis tests. ellipse() from th...

Computing Confidence Intervals for Common IR Measures

Confidence intervals quantify the uncertainty in an average and offer a robust alternative to hypothesis testing. We measure the performance of standard and bootstrapped confidence intervals on a number of common IR measures using several TREC and NTCIR collections. The performance of an interval is its empirical coverage of the estimated statistic. We find that both standard and bootstrapped i...
