Let Mt be a vector martingale and M t denote its predictable quadratic variation. In this paper we present a bound for the probability that z \* M -1 t Mt ΒΏ z \* M -1 t z with a ΓΏxed vector z and discuss some of its applications to statistical estimation in autoregressive and linear di usion models.
