  Recently, a metal-insulator transition (MIT) was found in the anisotropic
Anderson model of localization by transfer-matrix methods (TMM). This MIT has
been also investigated by multifractal analysis (MFA) and the same critical
disorders $W_c$ have been obtained within the accuracy of the data. We now
employ energy level statistics (ELS) to further characterize the MIT. We find a
crossover of the nearest-neighbor level spacing distribution $P(s)$ from GOE
statistics at small disorder indicating metallic behavior to the Poisson
distribution at large disorder characteristic for localized states. An analysis
of the system size dependence of the spectral rigidity $\Delta_3(L)$ confirms
the values of $W_c$ from TMM and MFA.
