Examples

>>> import openturns as ot
>>> import otsliced
>>> N = 100
>>> X = ot.Normal([0.0] * 2, [0.1] * 2).getSample(N)
>>> X += [[-i / (N - 1), 2 * i / (N - 1)] for i in range(N)]
>>> X = X - X.computeMean()
>>> f = ot.SymbolicFunction(['x1', 'x2'], ['4*(x1+2*x2)+2'])
>>> Y = f(X) + ot.Normal(0.0, 0.2).getSample(N)
>>> algo = otsliced.SlicedInverseRegression(X, Y)
>>> algo.run()
>>> transformation = algo.getResult().getTransformation()
