snowflake.snowpark.functions.skew¶

snowflake.snowpark.functions.skew(e: Union[Column, str]) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.26.0/snowpark-python/src/snowflake/snowpark/functions.py#L1096-L1111)¶

Returns the sample skewness of non-NULL records. If all records inside a group are NULL, the function returns NULL.

Example::

>>> from snowflake.snowpark.types import DecimalType
>>> df = session.create_dataframe(
...     [10, 10, 20, 25, 30],
...     schema=["a"]
... ).select(skew("a").cast(DecimalType(scale=4)))
>>> df.collect()
[Row(CAST (SKEW("A") AS NUMBER(38, 4))=Decimal('0.0524'))]
