I was not able to move the new classes to `experimental`. This was done in 29d054f59f77978b93f739d942d151d8c056c94c but it makes the unit test `t_LinearModelValidation_std.py` fail because the second input argument of...

@jschueller : I have an error with some unused variable: ``` lib/src/Uncertainty/Algorithm/MetaModel/FunctionalChaos/FunctionalChaosValidation.cxx:147:21: error: unused variable ‘indicesTrain’ [-Werror=unused-variable] 147 | const Indices indicesTrain(splitter.generate(indicesTest)); ``` Actually, the output of `splitter.generate()` is not...

I have an error that I cannot understand. Everything is fine before the LinearModelValidation is in `experimental`. After I moved the `LinearModelValidation` class to `experimental` in 8d94f0f9590e9c9ce0893f4c1e9a02f7a3c3c1ac, I got this...

You mean [CMakeLists.txt](https://github.com/openturns/openturns/blob/69816dc8b5c3319666dc917f1fa0b42e55195ed0/python/src/CMakeLists.txt#L875). I will try this.

@jschueller : We are stuck here on the experimental issue. Do you have any idea?

> which issue ? If the LinearModelValidation and FunctionalChaosValidation are put in the experimental module, LinearModelValidation fails to run while setting arguments to ctor (otexp.LinearModelValidation() is ok)

> the modules of the argument classes probably need to be added to experimentail_module.i (before LinearModelValidation inclusion) Here is my analysis: - I need to import LinearModelResult, but this is...
