Was trying to fit isotonic regression with non-trivial y_min and y_max:
In [*17*]: X
Out[*17*]:
array([ 1.26336413, 1.31853693, -0.57200917, 0.3072928 , -0.70686507,
-0.17614937, -1.59943059, 1.05908504, 1.3958263 , 1.90580318,
0.20992272, 0.02836316, -0.08092235, 0.44438247, 0.01791253,
-0.3771914 , -0.89577538, -0.37726249, -1.32687569, 0.18013201])
In [*18*]: iso.isotonic_regression(X, y_min=0, y_max=0.1)
Out[*18*]:
array([-0.00826919, -0.00826919, -0.00826919, -0.00826919, -0.00826919,
-0.00826919, -0.00826919, 0.10449344, 0.10449344, 0.10449344,
0.10449344, 0.10449344, 0.10449344, 0.10449344, 0.10449344,
0.10449344, 0.10449344, 0.10449344, 0.10449344, 0.10449344])
The solution does not satisfy the bounds that each entry should be in
[0,0.1]
