A comparison of some confidence intervals for a binomial proportion based on a shrinkage estimator

open access: yesOpen Mathematics, 2023
Confidence intervals are valuable tools in statistical practice for estimating binomial proportions, with the most well-known being the Wald and Clopper-Pearson intervals.

Fixed accuracy confidence intervals for variance under first-order stationary autoregressive processes

open access: yesResearch in Statistics
A sequential procedure is developed to construct a fixed accuracy confidence interval (CI) of the common unknown variance of the random observations, where the observations arise from a first-order stationary autoregressive (AR(1)) process with a ...
