In statistics, the delta method is a result concerning the approximate probability distribution for a function of an asymptotically normal statistical estimator from knowledge of the limiting variance of that estimator. ==Univariate delta method== While the delta method generalizes easily to a multivariate setting, careful motivation of the technique is more easily demonstrated in univariate terms. Roughly, if there is a sequence of random variables satisfying : where ''θ'' and ''σ''2 are finite valued constants and denotes convergence in distribution, then : for any function ''g'' satisfying the property that exists, is non-zero valued, and is polynomially bounded with the random variable.〔Oehlert, G.
