Try fitting it with a Johnson function -- see SuppDists. If you can fit it you will then be able to use the functions in SuppDists just as you can for any other distribution supported by R.

Hi there,

Sorry if this is a rather loing post. I have a simple list of single
feature data points from which I would like to generate a probability
that an unseen point comes from the same distribution. To do this I am
trying to estimate the probability density of the list of points and
use this to generate a probability for the new unseen points. I have
managed to use the R density function to generate the density estimate
but have not been able to do anything with this - i.e. generate a
rpobability that a new point comes from the same distribution. Is
there a function to do this, or am I way off the mark using the
density function at all?

Thanks in advance,

Brian.
