Event manipulation
==================

In this example we are going to define an Event from a scalar variable :math:`Y` in the form:

.. math::
   Y > T

with :math:`T` a scalar threshold



.. code-block:: default

    from __future__ import print_function
    import openturns as ot
    import openturns.viewer as viewer
    from matplotlib import pylab as plt
    ot.Log.Show(ot.Log.NONE)








Create model f(x) = x1 + 2*x2


.. code-block:: default

    model = ot.SymbolicFunction(['x1', 'x2'], ['x1+2*x2'])

    # Create the input distribution and random vector X
    inputDist = ot.Normal(2)
    inputDist.setDescription(['X1','X2'])

    inputVector = ot.RandomVector(inputDist)

    # Create the output random vector Y=f(X)
    outputVector = ot.CompositeRandomVector(model, inputVector)








Create the event Y > 3


.. code-block:: default

    threshold = 3.0
    event = ot.ThresholdEvent(outputVector, ot.Greater(), threshold)








Realization as a Bernoulli


.. code-block:: default

    print('realization=' , event.getRealization())





.. rst-class:: sphx-glr-script-out

 Out:

 .. code-block:: none

    realization= [0]




Sample of 10 realizations as a Bernoulli


.. code-block:: default

    print('sample=' , event.getSample(10))





.. rst-class:: sphx-glr-script-out

 Out:

 .. code-block:: none

    sample=     [ y0 ]
    0 : [ 0  ]
    1 : [ 0  ]
    2 : [ 0  ]
    3 : [ 1  ]
    4 : [ 0  ]
    5 : [ 0  ]
    6 : [ 0  ]
    7 : [ 0  ]
    8 : [ 0  ]
    9 : [ 0  ]




Build a standard event based on an event


.. code-block:: default

    standardEvent = ot.StandardEvent(event)
