Hi Pamphile,
Could you please provide us a script that reproduce the error? It looks very
strange, as this class is tested in more than 10 unit tests and is extensively
used in industrial studies. BTW, ot.ComposedDistribution is by no means
restricted to the independent copula as your comment could suggest.
Please note that it is not the physical space distribution which is checked by
the GaussProductExperiment class, but the distribution defining the functional
basis. You should use either OrthogonalProductPolynomialFactory or
OrthogonalProductFunctionFactory to build your multivariate basis from 1D
orthogonal bases to insure that the resulting multivariate distribution has an
independent copula.
Please give me a feedback on this problem ASAP.
Cheer

Hi Regis,
On the 1.10, I get this error calling the FunctionalChaosAlgorithm:
File
"/Users/roy/Applications/miniconda3/envs/batman3/lib/python3.6/site-packages/openturns/metamodel.py",
line 3849, in __init__ this =
_metamodel.new_FunctionalChaosAlgorithm(*args)TypeError:
InvalidArgumentException : Error: the GaussProductExperiment can only be used
with distributions having an independent copula.
But this was working on 1.9. I do not understand the issue as the distribution
is an ot.ComposedDistribution. I tried to explicitly add
ot.IndependentCopulawithout any change.
Thanks in advance,
Pamphile ROY
