skew(self, **kwargs)
A minimum of three periods is required for the rolling calculation.
For NumPy compatibility and will not have an effect on the result.
Return type is the same as the original object with np.float64
dtype.
Calculate the expanding unbiased skewness.
pandas.DataFrame.expanding
Calling expanding with DataFrames.
pandas.DataFrame.skew
Aggregating skew for DataFrame.
pandas.Series.expanding
Calling expanding with Series data.
pandas.Series.skew
Aggregating skew for Series.
scipy.stats.skew
Third moment of a probability density.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
