In statistics, a pivotal quantity or pivot is a function of observations and unobservable parameters such that the function's probability distribution does not depend on the unknown parameters (including nuisance parameters). One of the simplest pivotal quantities is the z-score; given a normal distribution with and variance, and an observation x, the z-score: has distribution a normal distribution with mean 0 and variance 1. 5.1 The pivotal quantity method; 5.2 Confidence intervals for normal populations. Therefore, selection of either the generalized pivotal quantity or -content (0.9) method for an analytical method validation depends on the accuracy of the analytical method. to sample estimates.
