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.}, keywords = {lattice field theory (INSPIRE) / covariance (INSPIRE) / Chi-squared test (autogen) / Goodness of fit (autogen) / Autocorrelations (autogen)}, cin = {$Z_ZPPT$}, ddc = {530}, cid = {$I:(DE-H253)Z_ZPPT-20210408$}, pnm = {611 - Fundamental Particles and Forces (POF4-611)}, pid = {G:(DE-HGF)POF4-611}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)16}, eprint = {2209.14188}, howpublished = {arXiv:2209.14188}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2209.14188;\%\%$}, UT = {WOS:000908997300001}, doi = {10.1016/j.cpc.2022.108643}, url = {https://bib-pubdb1.desy.de/record/482723}, }
