Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
dataframe.corrwith() is used to compute pairwise correlation between rows or columns of two DataFrame objects. If the shape of two dataframe object is not same then the corresponding correlation value will be a
Syntax: DataFrame.count(axis=0, level=None, numeric_only=False)
other : DataFrame
axis : 0 or ‘index’ to compute column-wise, 1 or ‘columns’ for row-wise
drop : Drop missing indices from result, default returns union of all
Returns: correls : Series
Note: The correlation of a variable with itself is 1.
Example #1: Use
corrwith() function to find the correlation among two dataframe objects along the row axis
Now find the correlation among the columns of the two data frame along the row axis.
The output series contains the correlation between the three columns of two dataframe objects respectively.
Example #2: Use
corrwith() function to find the correlation among two dataframe objects along the column axis
The output series contains the correlation between the four rows of two dataframe objects respectively.
