Central limit theorem for sum

WebIf we divide that sum by n, the second fact tells us it’s variance becomes n * σ² / n² = σ² /n. As a final note, almost all datasets you’ll encounter follow that central limit theorem, but there are a few edge cases that converge at different rates (like the Cauchy distribution). Probably don’t have to worry about those too much. WebThis is contrary to Gaussian sums where, as we stated earlier, each term contributes essentially equally to the sum. Thus, the central limit theorem cannot be applied to power-law distributions. The generalized central limit theorem is an extension of the classical central limit theorem, which was developed to deal with sums of power-law random ...
