In order to achieve the expression like "Power($close, Rank($close, 14))" which is fairly common in fomulla alpha.

I guess we could use following code:

class Power(NpPairOperator): def __init__(self, feature_left, feature_right): super(PairPower, self).__init__(feature_left, feature_right, "power")

Finally, we could add a rpow magic method to Expression class

According to @rspadim, functions in entropy.py could use numpy array instead of strings, as it's better to numba.

Guide on how to implement this is available in the comments in PR #311 .
