  We study the critical behavior of the Anderson localization-delocalization
transition in corner-sharing tetrahedral lattices. We compare our results
obtained by three different numerical methods namely the multifractal analysis,
the Green resolvent method, and the energy-level statistics which yield the
singularity strength, the decay length of the wave functions, and the
(integrated) energy-level distribution, respectively. From these measures a
finite-size scaling approach allows us to determine the critical parameters
simultaneously. With particular emphasis we calculate the propagation of the
statistical errors by a Monte-Carlo method. We find a high agreement between
the results of all methods and we can estimate the highest critical disorder
$W_\mathrm{c}=14.474(8)$ at energy $E_\mathrm{c}=-4.0$ and the critical
exponent $\nu=1.565(11)$. Our results agree with a previous study by Fazileh et
al. but improve accuracy significantly.
