โœฆ Synopsis


A Central Limit Theorem for a triangular array of row-wise independent Hilbert-valued random elements with รฟnite second moment is proved under mild convergence requirements on the covariances of the row sums and the Lindeberg condition along the evaluations at an orthonormal basis. A Central Limit Theorem for real-valued martingale di erence arrays is obtained under the conditional Lindeberg condition when the row sums of conditional variances converge to a (possibly degenerate) constant. This result is then extended, รฟrst to multi-dimensions and next to Hilbert-valued elements, under appropriate convergence requirements on the conditional and unconditional covariances and the conditional Lindeberg condition along (orthonormal) basis evaluations. Extension to include Banach-(with a Schauder basis) valued random elements is indicated.

This paper provides an empirical central limit theorem (CLT) for exchangeable random variables when the norming constants in the regular CLT are โˆš nh(n) with h(n) a slowly varying function. The situation with norming constants of the form nh(n) is also discussed.
