A first-order Taylor approximation for the variance of a function of estimators. The standard fix for correct confidence intervals on ratio metrics.
In Statistics, the delta method is a method of deriving the asymptotic distribution of a random variable. It is applicable when the random variable being considered can be defined as a differentiable function of a random variable which is asymptotically Gaussian. More generally, the delta method applies to Hadamard directionally differentiable functionals of stochastic processes that converge to a limiting process.
