# pandas.api.typing.DataFrameGroupBy.corrwith

DataFrameGroupBy.corrwith(other, drop=False, method='pearson', numeric_only=False)

  Compute pairwise correlation.

  Deprecated since version 3.0.0.

  Pairwise correlation is computed between rows or columns of DataFrame with rows or columns of Series or DataFrame. DataFrames are first aligned along both axes before computing the correlations.

  Parameters:
    other DataFrame, Series

      Object with which to compute correlations.

    drop bool, default False

      Drop missing indices from result.

    method{‘pearson’, ‘kendall’, ‘spearman’} or callable

      Method of correlation:

      - pearson : standard correlation coefficient

      - kendall : Kendall Tau correlation coefficient

      - spearman : Spearman rank correlation

      - callable: callable with input two 1d ndarrays

          and returning a float.

    numeric_only bool, default False

      Include only float, int or boolean data.

      Changed in version 2.0.0: The default value of `numeric_only` is now `False`.

  Returns:
    Series

      Pairwise correlations.

    Compute pairwise correlation of columns.

  Examples

      >>> df1 = pd.DataFrame(
      ...     {
      ...         "Day": [1, 1, 1, 2, 2, 2, 3, 3, 3],
      ...         "Data": [6, 6, 8, 5, 4, 2, 7, 3, 9],
      ...     }
      ... )
      >>> df2 = pd.DataFrame(
      ...     {
      ...         "Day": [1, 1, 1, 2, 2, 2, 3, 3, 3],
      ...         "Data": [5, 3, 8, 3, 1, 1, 2, 3, 6],
      ...     }
      ... )

      >>> df1.groupby("Day").corrwith(df2)
               Data  Day
      Day
      1    0.917663  NaN
      2    0.755929  NaN
      3    0.576557  NaN
