So, when you go to the game, do you buy a hot dog, a beer and a banner before the first quarter? Do you buy them all from the same vendor? Do you go back during the half? Does the score impact how much money you spend on concessions? All

It is becoming more and more apparent that social media is a gold mine of unstructured data that is just waiting to be analysed so that the nuggets can be extracted. At SAS Global Forum, I was particularly impressed with the diversified use of sentiment analysis and the exploration that
Jenn Sykes (you probably remember her from this great sentiment analysis post last year about American Idol), presented Predicting Electoral Outcomes with SAS® Sentiment Analysis and SAS® Forecast Studio at SAS Global Forum 2012. In addition to predicting elections, Sykes tells Anna Brown from Inside SAS Global Forum, that there is a lot of unstructured data
A reader asked: I want to create a vector as follows. Suppose there are two given vectors x=[A B C] and f=[1 2 3]. Here f indicates the frequency vector. I hope to generate a vector c=[A B B C C C]. I am trying to use the REPEAT function
