I would check for missing values. If any variable has a missing value than the sum will also contain a missing value for that observation. So with many variables you often end up with a surprisingly large number of missing values. -- Maarten On Mon, Jul 23, 2012 at 7:50 PM, <cdenking@bidmc.harvard.edu> wrote: > > > Hello, > > I am hoping for some help creating the code for a scoring system: > I have several different variable.
