Abstract

cifunction computes and plots the confidence interval function (also referred to as the “confidence curve”, “P-value function”, and “consonance interval”). A CI-function is a graphical display of all possible CIs around a specified point estimate. The peak of the curve indicates the point estimate, and the concentration of the curve around the point estimate indicates the precision of the estimate. A narrow CI-function would result from a large study with high precision, and a broad CI-function would result from a small study that had low precision. CI functions convey much more of the essential information by indicating the range of values that are reasonably compatible with the observations, assuming the statistical model is correct. They can also show that the data do not contain the information necessary for reassurance about an absence of effect.
