InferenceAnalysis¶

class persalys.InferenceAnalysis(*args)¶

Perform a Kolmogorov goodness-of-fit test for 1-D continuous distributions.

Parameters

namestr: Name
designDesignOfExperiment: Design of experiments

Examples

>>> import openturns as ot
>>> import persalys
>>> ot.RandomGenerator.SetSeed(0)

Create the model:

>>> filename = 'data.csv'
>>> sample = ot.Normal(3).getSample(100)
>>> sample.exportToCSVFile(filename)
>>> model = persalys.DataModel('myDataModel', 'data.csv', [0, 1, 2])

Create the Inference Analysis:

>>> analysis = persalys.InferenceAnalysis('analysis', model)
>>> analysis.run()

Get the result:

>>> result = analysis.getResult()
>>> resultX0 = result.getFittingTestResultForVariable('X0')

Attributes

thisown: The membership flag
