dc.description.abstract | In a recent paper, Puech and co-workers compared K-band Tully–Fisher relations derived
for nearby and distant galaxies, respectively. They concluded that the two relations differ,
and deduced that there is evolution in the Tully–Fisher relations. The statistical comparison
between the two regression lines is re-examined, and it is shown that the statistical test used
gives non-significant results. It is argued that better results can be obtained by comparing
the ‘inverse’ Tully–Fisher relations, and it is demonstrated by two different methods that the
nearby- and distant-sample relations do indeed differ at a very high significance level. One
of the statistical methods described is non-parametric, and can be applied very generally to
compare linear regressions from two different samples. | en_US |
