Some limit theorems for the empirical process indexed by functions

SummaryLet,n≧1, be a sequence of classes of real-valued measurable functions defined on a probability space (S,,P). Under weak metric entropy conditions on,n≧1, and under growth conditions on we show that there are non-zero numerical constantsC1 andC2 such that where α(n) is a non-decreasing function ofn related to the metric entropy of. A few applications of this general result are considered: we obtain a.s. rates of uniform convergence for the empirical process indexed by intervals as well as a.s. rates of uniform convergence for the empirical characteristic function over expanding intervals.
