What's behind door #1? goats, cars or SAS Doc


For years mathematicians have been pondering the Monty Hall Problem – you know, the old TV show where you have 3 doors and behind one door is a car (or some nice prize) and behind the other two doors are goats (or some undesirable prize).

You pick door #1.  But Monty opens another door, say door #3, and it’s a goat. Then Monty asks you if you want to choose door #2. Do you go for door #2 or stick with door #1?  What are the probabilities you’d get the car if you choose #2?

I enjoyed many evenings as a child watching ‘Let’s Make a Deal’, hosted by Monty Hall, with my family.  Today I have a deal for you - one that offers no goats!  With the release of SAS 9.3, we now have available the SAS OnlineDoc® 9.3 PDF Files DVD. The SAS OnlineDoc 9.3 DVD contains over 130 titles, over 50,000 pages of SAS® documentation, and compares to the individual hardcopy book purchase price of over $2500.  As the economic doors squeeze our profits these days, we all need a deal. At only $29.95, let me assure you that if you program in SAS and if you do not always have access to the internet, this deal is for you!

PS. Speaking of goats, I’d like to share a photo of my friends with you. I drive by these goats on the way home from work every day. They live near the SAS Solar Farm on the North Carolina State University’s Meat Goat and Forage Systems Research and Educational unit.  They are so cute they make me smile – I hope they make you smile, too! I’d still prefer the door with the car, though.

  1. What a great deal! For that price, it certainly is worth it - saving ones time in having to find and download the .pdf files. And even though the goats are cute, I agree with picking the door with the car... :-)
