**two features**by "Pearson chi-square test of independence" and Cramer's V and Phi value. Now I have two questions and I appreciate it if anyone can help me:

1- to Expand my analysis to multivariate analysis what should I do and which test or models should I use?

2- Since I'm checking the association of all these features should I apply multiple comparison correction? If yes should I apply for example FDR on

**ALL**P-values or it is required to apply FDR separately on P-values corresponding to comparing every feature with others?

Thanks in advnace
