cudf.DataFrame.kurtosis#

DataFrame.kurtosis(axis=None, skipna=None, level=None, numeric_only=None, **kwargs)#

Return Fisher’s unbiased kurtosis of a sample.

Kurtosis obtained using Fisher’s definition of kurtosis (kurtosis of normal == 0.0). Normalized by N-1.

Parameters
axis: {index (0), columns(1)}

Axis for the function to be applied on.

skipna: bool, default True

Exclude NA/null values when computing the result.

Returns
Series or scalar
