class SobolSimulationResult(*args)

Sobol simulation result.

Gathers the results of a SobolSimulationAlgorithm algorithm.

Parameters:
fo_distDistribution

The random vector to study.

to_distDistribution

The function to study.

outer_samplingint

The number of iterations.

block_sizeint

The batch size.

Examples

>>> import openturns as ot
>>> ot.RandomGenerator.SetSeed(0)
>>> fo_dist = ot.Normal([0.154081,0.872087,0.0122877,0.0433801], [0.00982468,0.0302524,0.00911937,0.00926643], ot.CorrelationMatrix(4))
>>> to_dist = ot.Normal([0.16743,0.795477,0.0124454,0.045178], [0.0068919,0.00950876,0.00204324,0.0038844], ot.CorrelationMatrix(4))
>>> result = ot.SobolSimulationResult(fo_dist, to_dist, 250, 100)
>>> fo = result.getFirstOrderIndicesEstimate()
>>> to = result.getTotalOrderIndicesEstimate()
>>> fo_dist = result.getFirstOrderIndicesDistribution()
>>> to_dist = result.getTotalOrderIndicesDistribution()
>>> graph = result.draw()
