Test a discrete distributionΒΆ
In this example we are going to perform a Chi2 goodness-of-fit test for an 1-d discrete distribution.
import openturns as ot
ot.Log.Show(ot.Log.NONE)
Create data
distribution = ot.Poisson()
sample = distribution.getSample(30)
Fit a Poisson distribution
distribution = ot.PoissonFactory().build(sample)
Test the fitted distribution
result = ot.FittingTest.ChiSquared(sample, distribution, 0.01)
print("Conclusion=", result.getBinaryQualityMeasure(), "P-value=", result.getPValue())
Conclusion= True P-value= 0.3560857869884469
