Is it possible to standardize density probabilities?

[Francisco Franco]

Good afternoon, sorry if my question is a bit silly.

I am trying to compare different KDE. Graphically, the Y axis of each model (Probability Density) is not homogeneous between each case (in some its maximum value is 0.1 in others 0.4, etc.) which visually can be somewhat misleading. Is there a way to edit this scale to standardize it?

Not a silly question at all.

If you are showing these in a multi-plot (ie different KDE distributions) then you might try [ Edit > Format > Options > Normalise areas ] this will make the areas of the KDE's proportional to the probability. Using this - under [Edit > Adjust > Z-Axis] you can change the maximum value to scale the plots.

For single plots this is autoscaled to the same maximum height. If you want to do something with these I suggest using [View > Raw output ] and save the Modelled data as a csv file for plotting in other software.

Best wishes

Christopher
