Hubble diagram residuals as a function of SN properties for distances calculated with the redshift‐independent marginalization procedure in combination with the BATM method (top) and for those calculated from various redshift‐specific methods (bottom). There are no apparent biases in the redshift‐independent distances as a function of extinction (values taken from Tonry et al. 2003), redshift, or light‐curve shape. In fact, for large values of ﹩A_{V}﹩, z, and MLCS Δ, the redshift‐independent distances appear to be slightly less biased than redshift‐specific methods.
