Stanley Fogleman says that SAS can be hard to learn on your own - not because it is a difficult language - but because of the various business requirements. In fact, even college students entering the workforce are often ill-prepared in some ways. That's why Fogleman believes that a SAS mentoring program
With the rapid changes in our education systems regarding new standards, assessments, accountability and evaluation, teachers are rightfully feeling the pressure of being underprepared. The majority of teachers were not trained or certified with these rigorous systems in place. Recognizing that higher education institutions need to play an active role
At the 2012 SAS Global Forum, one of the questions from a user was about showing the original data used for the box plot. While you can use outliers in conjunction with the box features to get a feel for the data, for some situations you may need to see exactly
SAS already has some cool mobile Business Intelligence apps. Now, Scott McQuiggan tells Anna Brown, in this Inside SAS Global Forum interview, that you can view the really cool high-performance analytics reports that you've created on your desktop - right from your mobile device. Check this out!!
In statistical programming, I often test a program by running it on a problem for which I know the correct answer. I often use a single expression to compute the maximum value of the absolute difference between the vectors: maxDiff = max( abs( z-correct ) ); /* largest absolute difference
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
Recently I posted an article on this blog on how to create bar charts with log response axes in response to a question by a user. This generated some feedback suggesting that bar charts should not be used with log response axes or with a baseline of anything other than
According to Carlos André Reis Pinheiro, social networks in communications are easy to understand and detect, so Oi Telecommunications chose that route first when trying to detect fraud. Community detection for fraud proved to be somewhat different. It is a progressive search, from looking at the entire network to looking
A SAS user (who lives in the the US) emailed me a question about SAS functions. He was reading UTC (Coordinated Universal Time) datetime values from server logs, and to make future calculations and comparisons easier, he wanted to transform the value to local datetime. The INTNX() function worked great, but
Congratulations to all of you who presented at SAS Global Forum. It takes a lot of hard work to put together the research, write a paper and presentation, and then stand on stage and present to a crowd of people you have never met. You are amazing. From all of
If you have ever searched social media - Twitter, the blogsphere, Facebook, LinkedIn, Pinterest - for your favorite topic (I'm guessing it's baby penguins or monster truck racing), then you know that it can be like searching for a needle in a haystack. Imagine how law enforcement officers feel: They
To a statistician, the DIF function (which was introduced in SAS/IML 9.22) is useful for time series analysis. To a numerical analyst and a statistical programmer, the function has many other uses, including computing finite differences. The DIF function computes the difference between the original vector and a shifted version
Google's Chief Economist Hal Varian says the sexiest job of this decade will be statistician. Anna Brown interviewed George Hurley, a Senior Research Manager, to find out what the big deal is. Take a look at his answer and then tell me why you think being a statistician is the hot
