Now you have the following properties for random vector X and a (non-random) … Here, the delta method is presented in a rough way, but it is enough to see the relation with the variance-stabilizing transformations. To see a more formal approach see delta method. Let be a random variable, with and . Define , where is a regular function. A first order Taylor approximation for is: From the equation above, we obtain:
