The most widelyknown method is the normal approximation, but it may have serious shortcomings if n is small or if the proportion isclose to 0 or 1. Alternative methods have been developed and this paper presents 12 different methods forconstructing such confidence intervals, 11 of which are ...
Re: interpretation confidence intervals for proportions Posted 03-14-2022 06:07 AM (783 views) | In reply to mjkop56 I would expect to see such detail if I had 3 or more categories such as with race or age groups. If you have a strictly binomial proportion then would wo...

Confidence Intervals - Basic Properties Right, so a confidence interval is basically a likely range of values for a parameter such as a population correlation, mean or proportion. Therefore, wider confidence intervals indicate less precise estimates for such parameters. Three factors determine the width...
The practical merits of Neyman-Pearson confidence intervals versus hypothesis tests (especially p-values) are discussed. In the one-parameter case, confidence intervals convey much more comprehensible information, especially for the ultimate users of statistics. For more complicated inferences, p-values ...

From the asymptotical normality of the maximum likelihood estimators, confidence intervals can be obtained. However, these results might not be very accurate for small sample sizes and/or with large proportion of censored observations. Considering the three-parameter Weibull distribution for the failure...
