StratifiedExperiment¶

class StratifiedExperiment(*args)¶

Base class for stratified experiments.

Parameters:

center, levelstwo sequences of float: Sequences which have different meanings according to the nature of the stratified experiment: Axial, Composite, Factorial or Box (see corresponding documentation).

Notes

A StratifiedExperiment object can be used only through its derived classes:

Methods

`generate`()	Generate points according to the type of the experiment.
`getCenter`()	Get the center of the stratified experiment.
`getClassName`()	Accessor to the object's name.
`getLevels`()	Get the levels of the stratified experiment.
`getName`()	Accessor to the object's name.
`hasName`()	Test if the object is named.
`setCenter`(center)	Set the center of the stratified experiment.
`setLevels`(levels)	Set the levels of the stratified experiment.
`setName`(name)	Accessor to the object's name.

__init__(*args)¶

generate()¶

Generate points according to the type of the experiment.

Returns:

sampleSample: The points which constitute the design of experiments. The sampling method is defined by the nature of the experiment.

Examples

>>> import openturns as ot
>>> ot.RandomGenerator.SetSeed(0)
>>> myExperiment = ot.Experiment(ot.MonteCarloExperiment(ot.Normal(2),5))
>>> print(myExperiment.generate())
    [ X0        X1        ]
0 : [  0.608202 -1.26617  ]
