WebApr 12, 2024 · The percentage of successful patients will be calculated at the end of step 1 if the number of successes is not compatible with continuing the study or at the end of step 2 otherwise. The 95% confidence interval of this percentage will be estimated from an exact binomial distribution. WebAlso see Collett (1991) for more information about exact binomial confidence limits. Because this is a discrete problem, the confidence coefficient (or coverage probability) of the exact (Clopper-Pearson) interval is not exactly but is at least (). Thus, this confidence interval is conservative. external tools for ssms

"Webpractice, however, the Exact interval produces overly conservative confidence intervals with true coverage closer to 99% when the nominal confidence is 95%. It is especially vulnerable to this overly conservative nature when samples sizes are small (n <15) (Agresti and Coull, 1996). Thus, Exact intervals are too wide and Wald intervals are too ...
