It is known that standard techniques for denoising, developed for diffusion settings, do not work in this case. For this reason, we provide an extension of the pre-averaging method which allows for a consistent estimation of the Lévy distribution function even under microstructure noise. Interestingly, the asymptotic behaviour of the novel estimator is the same as in the no-noise case. This is in sharp contrast to what is known for diffusions.enDiscussion Paper / SFB 823;16/2013Lévy processmicrostructure noisenonparametric statisticsweak convergence310330620working paper
