    Multiple regression analysis: linear or logistic?




    Hello!

    I have a question regarding multiple regression analysis: for numerical variable I should use linear regression and for dichotomous variables I should use logistic regression. But if I have numerical and dichotomous variables, which regression should I use? Thank you!

    It depends on your dependent variable. The Y. If that is linear you use linear regression (generally although there are many special cases like using poisson regression for count data etc). If you dependent variable is dichotomous you use logistic regression.

    It does not matter what form your predictor variables are. You can have only one variable as the dependent variable and obviously it can not be linear and dichotomous.
