Instead, they need to be recoded into a series of variables which can then be entered into the regression model.

## How do you test for Multicollinearity for categorical variables?

For a categorical and a continuous variable, multicollinearity can be measured by t-test (if the categorical variable has 2 categories) or ANOVA (more than 2 categories).

## Can you correlate two categorical variables?

Most recent answer. You can use chi square test or Cramer’s V for the categorical variables. The correlation between two numeric variables can be measured with Spearman coefficient. … If the categorical variable has 2 levels, point-biserial correlation is used (equivalent to the Pearson correlation).
