  This paper reports a search for spatial clustering of the arrival directions
of high energy muon neutrinos detected by the ANTARES neutrino telescope. An
improved two-point correlation method is used to study the autocorrelation of
3058 neutrino candidate events as well as cross-correlations with other classes
of astrophysical objects: sources of high energy gamma rays, massive black
holes and nearby galaxies. No significant deviations from the isotropic
distribution of arrival directions expected from atmospheric backgrounds are
observed.
