snowflake.snowpark.functions.regr_sxy¶

snowflake.snowpark.functions.regr_sxy(y: Union[Column, str], x: Union[Column, str]) → Column[source]¶

Returns REGR_COUNT(expr1, expr2) * COVAR_POP(expr1, expr2) for non-null pairs.

Example:

>>> df = session.create_dataframe([[10, 11], [20, 22], [25, None], [30, 35]], schema=["v", "v2"])
>>> df = df.filter(df["v2"].is_not_null())
>>> df.group_by("v").agg(regr_sxy(df["v"], df["v2"]).alias("regr_sxy")).collect()
[Row(V=10, REGR_SXY=0.0), Row(V=20, REGR_SXY=0.0), Row(V=30, REGR_SXY=0.0)]
