Just curious:

What is the formal meaning of "controlling for certain variables" in multivariate logistic regression analysis?

I'm referring to statements like (paraphrase): when controlled for age, IT proffesionals earn $2,500 more than university computer science professors.

I imagine one randomizes the choices for the variables being controlled?
