interactive dummies

Dimitris Nikolaou
Hello to everybody!

I have used in my regression a dummy for marriage: married, single, divorced
(the base dummy), sex (female=0 and male=1), and if someone has any
children: child, nochild(base dummy) and other. I created an interactive
dummy if someone is man and married (sex*married) and another ifsomeone is a
man and has children (man*child).
My first question is to which I compare each one of them. For example for
the first case I compare the married man to those men not married or to
women?
Also, I will use in my regression both the interactive and the first dummies
(sex*married, se and married)?
Finally, can I use interactive dummies for both sexes at the same time? By
this I mean, can I have in my regression male*married, male*child,
woman*married and woman*child?

Thank you very much for your valuable help!
Dimitris!
