Description
We present an update of the analysis of the leading order hadronic contribution to the muon g-2 using a high statistics evaluation of the vacuum polarization function (VPF) with O(a)-improved $N_f=2$ Wilson fermions. Partially twisted boundary conditions are used to increase the number of available $Q^2$ points. We employ an extended frequentist's method to study the systematic errors arising from the $Q^2$ dependence of the VPF as well as various ans\"atze for the continuum and chiral extrapolation. We present preliminary results for $a_\mu^\mathrm{HLO}$ including the valence contributions of u,d,s and c quarks.
