I'm creating a regression model and I want to test if some co-variables are linear or co-dependent? I am thinking, among other things, of '' access to land '' and '' possession of livestock ''.

Which test can I use to show the **collinearity between two categorical variables?**

Thanks

Collinearity is not the right word for categorical variables.

p<0.05 indicates lack of independence.

The Chi-squared test in PROC FREQ can test the independence of two categorical variables.

oh ok, thank u so much for ur answer!

Then if the p-value of the chi-square test is less than 0.05 ==> Can I assume that there is a collinearity between the two variables

and if the p-value is higher than 0.05 ==> then the 2 variables are independent (no collinearity)

Is this right!?
