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 ...
