WebMay 26, 2024 · In the present article, we obtain new explicit estimates for accuracy of approximation in the central limit theorem (CLT). We construct these approximations … WebI imagine the "ceiling" where the CLT approximation starts getting worse would be dependent on your sample data and its distribution. Provided you use a SRS with replacement, then your random sample will be IID so the CLT applies. It doesn't matter whether your population is finite or infinite. If I use SRS with replacement, then each …
