在 Python 中如何做多于 2 个变量的多列之间的相关性？

Question

I have a Pandas Dataframe like so:

id    cat1    cat2    cat3    num1    num2
1     0       WN      29      2003    98
2     1       TX      12      755     76
3     0       WY      11      845     32
4     1       IL      19      935     46

I want to find out the correlation between cat1 and column cat3 , num1 and num2 or between cat1 and num1 and num2 or between cat2 and cat1, cat3, num1, num2

When I use df.corr() it gives Correlation between all the columns in the dataframe, but I want to see Correlation between just these selective columns detailed above.

How do I do that in Python pandas?

A Thousand thanks in advance for your answers.

Answer 1

I tried the following and it worked:

features1=list(['cat1','cat2','cat3'])
features2=list(['Cat1', 'Cat2','num1','num2'])

df[features1].corr()
df[features2].corr()

Good way to select the columns based on the need when you have a very high number of variables in your dataset.
