Abstract

Let(X i ) be a martingale difference sequence. LetY be a standard normal random variable. We investigate the rate of uniform convergence
$$P\left\{ {\sum\limits_{k = 1}^n {X_k } > \sqrt n r} \right\}/P\{ Y > r\} \to 0asn \to \infty ,$$
asn → ∞, over 0⩽r⩽o(n1/6) in the case of bounded martingale differences. The results are applied to prove large deviations for the ‘baker transformation’. Moderate deviations for martingales are also discussed.
