  The leading hadronic contribution to the muon anomalous magnetic moment is
given by a weighted integral over euclidean momentum of the hadronic vacuum
polarization. This integral is dominated by momenta of order the muon mass.
Since the finite volume in lattice QCD makes it difficult to compute the vacuum
polarization at a large number of low momenta with high statistics (combined
with the fact that one cannot compute it at zero momentum), a parametrization
of the vacuum polarization is required to extrapolate the data. A much used
functional form is based on vector meson dominance, which introduces model
dependence into the lattice computation of the magnetic moment. Here we
introduce a model-independent extrapolation method, and present a few first
tests of this new method.
