This is a statistical analysis of data on type SN Ia supernovae from which it was concluded during 1998–1999 that the expansion of the universe is accelerating. The hypothesis that there exists a standard value of the red shift in the spectra of type SN Ia supernovae that corresponds to a standard value of the absolute stellar magnitude for distance determinations is examined.

Notes
The χ2 statistic is actually the likelihood function of a mixture of gaussian distributions. This violates the condition of statistical uniformity of the data with respect to their dispersions (the homoscedacity condition).
The abbreviations for the names of these methods contain the letters MMK from the maximum compactness method (from the name of the basic method of Ref. 12).
