There is no problem with using a combination of dummy and
continuous variables. If you are unsure you can read the
original article, which is not bad for an original article:
Heise, David R. (1972). Employing nominal variables, induced
variables, and block variables in path analysis. Sociological
Methods & Research, 1(2): 147--173.
Alternatively I just gave a talk about this at the UK Stata
Users' Group Meeting, and the slides are downloadable from my
