Framingham has been churning out risk scores since the 1960s! Which one do you want? Their papers usually give a step by step calculation.
I should note that the coefficient for smoking in Framingham is surprisingly small. And also that Framingham is actually a family study, but this does not seem to have been taken into account in the models. Familial clustering of smoking and risk may account for the strange odds ratio.
What I meant was that Framingham has published the formulas for their risk functions in each of the papers that described the function. You can just calculate them in SPSS as computed variables using the formula.
In other words, Abigail Bailey, can you share an article or website that has the equation you want to use in SPSS? The names of the relevant variables in your dataset would be useful too.
