If you got missing values in the result, you have missing values in one or more of the variables used. There's no advice I can see except to investigate the structure of missing values and decide what your rules are given missing values. Nick n.j.cox@durham.ac.uk cdenking@bidmc.harvard.edu I am hoping for some help creating the code for a scoring system: I have several different variable. All my variables except for one are bina= ry (1/0) and the one is 2/1/0. They are coded as float variables. For every ID I am trying to create a total score with the sum of the score = for variable1 + variable2 + variable3 + 8* variable4 + 4* variable5 + 2* va= riable6 - 3*variable7. If variable1 is 1 then it adds to the score, if it 0= then it doesn't. If variable7 is yes then I want subtract 3 points. I tried with generate total_score=3D variable1 + variable2 + variable3 + 8* variable4 + = 4* variable5 + 2* variable6 - 3*variable7 but only got missing values. What do I need to do?
