Correction : November 24 , 2005 , Thursday Because of an editing error , an article on Friday about a contention by William F. Weld , the former chief executive of a for-profit vocational school , that the federal government drove the school into bankruptcy referred incorrectly to the position that Rudolph W. Giuliani , the former New York mayor , holds with Mr. Weld 's investment firm , Leeds Weld & Company .
