| Abstract: |
Although the use of histograms implies loss of information due to the fact that
the actual data are replaced by the central values of the considered intervals,
these graphical representations are commonly employed in scientific
communication, particularly in astrophysics. This work explores the
possibility of applying the Anderson-Darling test, a well-known test suitable
for the comparison of continuous data sets, to the comparison of data in
histogram format. For that purpose the data within each histogram interval are
resampled, using the information provided by the frequencies of
the adjacent intervals. Several resampling strategies have been examined by
the comparison of histograms built from simulated data following
a normal distribution. |
