We describe a method and a computer program, written in JavaScript, for calculating confidence intervals. The method uses Taylor's series to approximate the standard errors of a post-test probability and threshold probabilities and, from them, to obtain the associated confidence intervals. This method is valid if the variables of interest are stochastically independent.
