چکیده
Interpreting entropy as a prior probability suggests a universal but “purely empirical” measure of “goodness of fit”. This allows statistical techniques to be used in situations where the correct theory — and not just its parameters — is still unknown. As developed illustratively for least-squares nonlinear regression, the measure proves to be a transformation of the R statistic. Unlike the latter, however, it diminishes rapidly as the number of fitting parameters increases.

35 Eclipsing binaries presenting unambiguous total eclipses were selected from a subsample of the list of Wyrzykowski et al. (2003). The photometric elements are given for the I curve in DiA photometry, as well as approximate Teff and masses of the components. The interest of these systems is stressed in view of future spectroscopic observations.
