      abstract     = {Observables in particle physics and specifically in lattice
                      QCD calculations are often extracted from fits. Standard
                      $\chi^2$ tests require a reliable determination of the
                      covariance matrix and its inverse from correlated and
                      auto-correlated data, a challenging task often leading to
                      close-to-singular estimates. These motivate modifications of
                      the definition of $\chi^2$ such as uncorrelated fits. We
                      show how the goodness-of-fit measured by their p-value can
                      still be estimated robustly for a broad class of such fits.},
