Méthode pandas.DataFrame.kurt

Signature de la méthode kurt

def kurt(self, axis: 'Axis | None' = 0, skipna: 'bool' = True, numeric_only: 'bool' = False, **kwargs) 

Description

help(DataFrame.kurt)

Return unbiased kurtosis over requested axis.

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.
    For `Series` this parameter is unused and defaults to 0.

    For DataFrames, specifying ``axis=None`` will apply the aggregation
    across both axes.

    .. versionadded:: 2.0.0

skipna : bool, default True
    Exclude NA/null values when computing the result.
numeric_only : bool, default False
    Include only float, int, boolean columns. Not implemented for Series.

**kwargs
    Additional keyword arguments to be passed to the function.

Returns
-------
Series or scalar

            Examples
            --------
            >>> s = pd.Series([1, 2, 2, 3], index=['cat', 'dog', 'dog', 'mouse'])
            >>> s
            cat    1
            dog    2
            dog    2
            mouse  3
            dtype: int64
            >>> s.kurt()
            1.5

            With a DataFrame

            >>> df = pd.DataFrame({'a': [1, 2, 2, 3], 'b': [3, 4, 4, 4]},
            ...                   index=['cat', 'dog', 'dog', 'mouse'])
            >>> df
                   a   b
              cat  1   3
              dog  2   4
              dog  2   4
            mouse  3   4
            >>> df.kurt()
            a   1.5
            b   4.0
            dtype: float64

            With axis=None

            >>> df.kurt(axis=None).round(6)
            -0.988693

            Using axis=1

            >>> df = pd.DataFrame({'a': [1, 2], 'b': [3, 4], 'c': [3, 4], 'd': [1, 2]},
            ...                   index=['cat', 'dog'])
            >>> df.kurt(axis=1)
            cat   -6.0
            dog   -6.0
            dtype: float64
