Examination of Variables Prior to Transformation ------------------------------------------------ AUTHOR: Thomas W. Findley, M.D., Ph.D. Kessler Institute for Rehabilitation W. Orange, N.J. 07052 SUPPORT: Comments and suggestions addressed to the author. The syntax for ^transfor.do^ is: ^do transfor^ var1 [var2] Alternatively: ^run transfor^ var1 [var2] where var1 is the variable you want transformed and var2 is an optional var- iable you want var1 graphed against. The program progresses through the "ladder of powers" and provides you with numeric information as well as graphic suggestions as to the "best" variable transform. Nine graphs are produced as ^.gph^ files. They are named ^trans1.gph^, ^trans2.gph^, etc. They are written over by subsequent runs; hence rename any you desire to keep. Code is provided, but commented out, to allow the student version of Stata to be used. The program code explains how to do this.
