Python GammaMuSigma Examples

Example #1

File: t_ParametrizedDistribution_std.py Project: sofianehaddad/openturns

#! /usr/bin/env python

import openturns as ot

parameters = ot.GammaMuSigma(0.1, 0.489898, -0.5)
distribution = ot.ParametrizedDistribution(parameters)

print("Distribution ", distribution)

# Is this distribution elliptical ?
print("Elliptical = ", distribution.isElliptical())

# Is this distribution continuous ?
print("Continuous = ", distribution.isContinuous())

# Test for realization of distribution
oneRealization = distribution.getRealization()
print("oneRealization=", oneRealization)

# Test for sampling
size = 10000
oneSample = distribution.getSample(size)
print("oneSample first=", oneSample[0], " last=", oneSample[size - 1])
print("mean=", oneSample.computeMean())
print("covariance=", oneSample.computeCovariance())

# Define a point
point = ot.Point(distribution.getDimension(), 1.0)
print("Point= ", point)

# Show PDF and CDF of point
