  The clustering properties of the highest energy cosmic rays and their
correlations with candidate sources are re-examined using the most recently
available AGASA data and a rigorous correlation analysis. The statistical
methodology incorporates some important points not considered in previous
studies. Results include small angle clustering significances consistent with,
but somewhat less than, earlier findings, a possible large scale anisotropy for
events with energies $E \approx 5 - 8 \times 10^{19} \mathrm{eV}$, and no
statistically significant cross correlations with BL Lacertae or blazars. A
marginally significant cross correlation exists for events with energies $E > 8
\times 10^{19} \mathrm{eV}$ with a set of Abell clusters, but no definitive
conclusion can yet be drawn from this result.
