LeastSquaresMetaModelSelectionFactory

class LeastSquaresMetaModelSelectionFactory(*args)

Least squares metamodel selection factory.

Available constructors:

LeastSquaresMetaModelSelectionFactory()

LeastSquaresMetaModelSelectionFactory(basisSeqFac)

LeastSquaresMetaModelSelectionFactory(basisSeqFac, fittingAlgo)

Parameters:
basisSeqFacBasisSequenceFactory

A basis sequence factory.

fittingAlgoFittingAlgorithm

A fitting algorithm.

Notes

Implementation of an approximation algorithm implementation factory which builds an ApproximationAlgorithm.

This class is not usable because it has sense only within the FunctionalChaosAlgorithm.

Examples

>>> import openturns as ot
>>> basisSequenceFactory = ot.LARS()
>>> fittingAlgorithm = ot.CorrectedLeaveOneOut()
>>> approximationAlgorithm = ot.LeastSquaresMetaModelSelectionFactory(
...                                     basisSequenceFactory, fittingAlgorithm)
