  The level-spacing distribution in the tails of the eigenvalue bands of the
power-law random banded matrix (PRBM) ensemble have been investigated
numerically. The change of level-spacing statistics across the band is examined
for different coupling strengths and compared to the density of states for the
different systems. It is confirmed that, by varying the eigenvalue region, the
same level-spacing statistics can be reached as by varying the coupling
strength.
