A Central Limit Theorem and Higher Order Results for the Angular Bispectrum
The angular bispectrum of spherical random fields has recently gained an enormous importance, especially in connection with statistical inference on cosmological data. In this paper, we provide expressions for its moments of arbitrary order and we use these results to establish a multivariate central limit theorem and higher order approximations. The results rely upon combinatorial methods from...
متن کاملA Functional Central Limit Theorem for The
In this paper, we present a functional fluid limit theorem and a functional central limit theorem for a queue with an infinity of servers M/GI/∞. The system is represented by a point-measure valued process keeping track of the remaining processing times of the customers in service. The convergence in law of a sequence of such processes after rescaling is proved by compactness-uniqueness methods...
متن کاملThe Local Limit Theorem: A Historical Perspective
The local limit theorem describes how the density of a sum of random variables follows the normal curve. However the local limit theorem is often seen as a curiosity of no particular importance when compared with the central limit theorem. Nevertheless the local limit theorem came first and is in fact associated with the foundation of probability theory by Blaise Pascal and Pierre de Fer...
متن کاملCentral Limit Theorem and Almost Sure Central Limit Theorem for the Product of Some Partial Sums
Let (Xn)n≥1 be a sequence of independent identically distributed (i.i.d.) positive random variables (r.v.). Recently there have been several studies to the products of partial sums. It is well known that the products of i.i.d. positive, square integrable random variables are asymptotically log-normal. This fact is an immediate consequence of the classical central limit theorem (CLT). This point...
متن کاملRecent Results on Refinements of the Central Limit Theorem
Let {X"} be a sequence of independent and identically distributed (i.i.d.) random vectors in Rk with zero mean vector and identity covariance matrix. The distribution Qn of the normalized sum n-'12(X1 + *-+ X") converges weakly to the k dimensional standard normal distribution (D. Although many important results on rates of convergence have been obtained in the past, most of them refer to appro...
