Abstract The Padé-Z2 stochastic estimator is used to calculate the fermion matrix determinants and the determinant ratios with an unbiased variational scheme. The results on an 83 x 12 lattice with Wilson action show that the determinant ratio with a relatively small number of Z2 noises (e.g., 400) can be estimated by using the unbiased subtractions.
