What Is the Delta Method?
Delta method is an analytic method for estimating the variance of a combination of random variants that themselves are normally distributed. We have this differentiable function with an infinite number of sums, which we call a Taylor series. And so usually we just take the first or the second Taylor series approximation and give it a standard error. But if we add those two parameters together, we can use Delta method to get what is the variance of the sum of two normally distributed random variants.
