As a ﬁrst-order remedy, we derive Edgeworth expansions for the RV-type estimators when the observations of the price process are noisy. What makes the situation unusual is that the errors (noises) are very small, and if they are taken to be of order O p(1), their impact on the Edgeworth expansion may be exaggerated. knives with resin coating
