Levy-cramer theorem

WebFeb 9, 2024 · Put S n = X 1 + ⋯ X n. Under these assumptions, the distribution of the random vector ( S n — n c) / n converges weakly to the centered normal distribution with covariance matrix Σ. The proof is as follows: Let Y = ( Y 1,..., Y n) be a normally distributed random with 0 means and covariance matrix Σ.
