Subject:      Relative risks and risk differences in SAS?
Content-Type: text/plain; charset="iso-8859-1"

Hi, 

I just got a request for relative risks- here is is:

Do you know if your statistics package can estimate relative risks and

risk differences based on odds ratios and known or estimated

population fraction of cases (prevalence)?  I was reading through a

paper by Gary King (http://gking.harvard.edu/files/abs/1s-abs.shtml)

and was wondering if the relative risk or risk reduction of having a

particular SNP would be easier to understand than just p-values or

odds ratios.  



I'm not familiar with this- does anyone know how this is done in SAS?
