Goodness-of-fit
test applied to weighted
logistic regression model
for gold deposits, Meguma
Terrane (Fig.
5.18a
). The
difference between
observed and estimated
relative frequencies is
plotted against the posterior
probability. The absolute
value of the largest
difference (¼0.0775) is less
than the Kolmogorov-
Smirnov statistic (¼0.1426)
indicating a good fit
