I'd like to check the correlation betwen continuous indipendent variables and a target categorical variable; so i thought of computing point-biserial correlation, but my data don't meet the assumptions (normality, homogeneity of variance...). Is there any alternative to point-biserial correlation to calculate the correlation between continuos and categorical variables?
