can multiple regression be applied when all variables are nomina binary dichotomoir.. ONE DV Y/N; 3 IV Y/N Can multiple regression be applied when all variables are nominal dichotomous?
Dependent variable: Y/N (binary)
3 Independent variables: Y/N (binary)

This would be an excellent situation to use a generalized linear model like logistic regression, since the outcome is binary. In the case where the outcome is continuous (perhaps with some other conditions), linear regression would be viable.
A key takeaway is that binary predictor variables present no challenge to linear and generalized linear models.
