How to find Correlation among more than two categorical variables



How can we calculate correlation or multi-collinearity among more than two categorical variables?
Is it neccessary to convert them into numerical variables?


@ved - You can calculate the using Chi-Square Test between two categorical variable and if you want to calculate for more than two variable you can find N by N matrix of all data.

Hope this helps!



N by N matrix doesn’t work in this case…Chi square test works only for 2 variable…If these were numerical varaibles then its easy to find correlation…
