Area normalisation of density estimates
In studies involving multiple samples, it is useful to normalise
the area under the density estimates to a common value.
The area under the KDE is reported in the Options →
Settings menu. When the normalise checkbox
is selected, the areas under the KDE, histogram (and PDP) are normalised
to the same value. In this case, the default histogram binwidth is reduced.
This value can, of course, be changed to any other value.
The area value can be accessed from the command line, facilitating the
generation and intercomparison of multiple samples.
