Abstract:
We investigated the application of resampling techniques to the statistical analysis
of the Brier score (B), and extended them to the statistical comparison of two Bs derived from the same set of patients. The re-sampling techniques are helpful in
the statistical analysis of B, and there are almost no differences between the jackknife method and the bootstrap
method in this analysis. Thus, we believe that B should be used more often as an index to evaluate probabilistic judgments in the
case in which the data sets for the assessment are “degenerate” as the “receiver operating
characteristic data sets.”
