Query: A multiscale autocorrelation function for anisotropy studies   In recent years many procedures have been proposed to check the anisotropy of
a dataset. We present a new simple procedure, based on a scale dependent
approach, to detect anisotropy signatures in a given distribution with
particular attention to small dataset. The method provides a good
discrimination power for both large and small datasets, even in presence of
strong contaminating isotropic background. We present some applications to
simulated datasets of events to investigate statistical features of the method
and present and inspect its behavior under both the null or the alternative
hypothesis.
