                  throws Exception

Returns natural logarithm of density estimate for given value based on given instance.

Parameters:

instance - the instance to make the prediction for.

value - the value to make the prediction for.

Returns:

the natural logarithm of the density estimate

Throws:

Exception - if the density cannot be computed
