If you did not provide more than half your support for the year, it depends on other factors; most importantly when did you move out of your father's home. If it was before July 3, then you almost certainly cannot be claimed by him.
The IRS has a worksheet that can be used to help with the support calculation. See: http://apps.irs.gov/app/vita/content/globalmedia/teacher/worksheet_for_determining_support_4012.pdf The support value of a home is the fair market rental value, divided by the number of occupants.
