%define OT_FittingAlgorithm_doc
"Fitting algorithm.

Available constructors:
    FittingAlgorithm(*fittingAlgoImp*)

Parameters
----------
fittingAlgoImp : a FittingAlgorithmImplementation
    A fitting algorithm implementation which is the
    :class:`~openturns.CorrectedLeaveOneOut` or :class:`~openturns.KFold`.

See also
--------
CorrectedLeaveOneOut, KFold

Notes
-----
FittingAlgorithm is the interface of the FittingAlgorithmImplementation.
This class is not usable because it has sense only whithin the
:class:`~openturns.FunctionalChaosAlgorithm`."
