Hi,

I've got access to Mathematica 8.0 and encountered a bug in CDF[owndistrib]:

with
d = TransformedDistribution[x/(1 + x), Distributed[x, UniformDistribution[{0, 1}]]]
I get a correct PDF via PDF[d,x] which integrates to a correct CDF using
Integrate[PDF[d, t], {t, -Infinity, x}].
But CDF[d, x] differs for 1/2 <= x <=1
(see attachment).

Has this been fixed in the minor upgrade?

Thanks,
Peter
