SAS software has long been used to help analyze 'risk' - what about using it to help determine your risk of being attacked by a vampire?!?
On a previous Halloween, I was the victim of a Vampire attack. Here's the photographic proof...
Being the most common O+ blood type, I thought I was at low risk of attack (with vampires allegedly preferring the more rare blood types, according to this report) -- but I guess a really hungry vampire will lower her standards from time to time.
So, what is your blood type, and how common or rare is it in the human population? Assuming that vampires prefer the more rare blood types, what is your risk of a vampire attack? And if there is geographical clustering of the rare blood types, might vampires be lured to those areas (assuming they use analytics to determine such things)?
I found some data about blood types by country, and plotted the values on a world map. Perhaps you can analyze these maps to help determine the rarity of your blood type, and whether you live in a vampire-prone area of the world. I've included small thumbnails of my maps below, and you can click on them to see the full size maps with html hover-text for each country:
