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
Many SAS customers are quickly adopting 64-bit versions of Microsoft Windows, and they are pleased-as-punch when they find a 64-bit version of SAS to run on it. They waste no time in deploying the new version, only to find that a few things don't work quite the same as they
Waynette is exhausted after everything she did at SAS Global Forum, so she asked me to write a blog post for her so she can take some time to rest up. ??? Hey, Waynette, like you think I’m a bundle of energy after chairing the event ??? I mean, I
Each time I attend the SAS Global Forum, I learn some tricks and this year was no different. Here're 4 tips that you might find useful for the conference next year and please leave yours in the Comments Section.
Last week I introduced this series. Today I begin to dive deeper into each of the four E's. First up? Enforcement. In 2009, there were 5.5 million police-reported traffic crashes. Law enforcement officers work diligently to prevent crashes by enforcing traffic safety laws pertaining to, among other things, seat belt
Now, we all know by now that I'm not a programmer (that makes me very sad sometimes and may frustrate some of you at times), but I know a good paper and presentation when I see one. Christopher Bost knows how to teach a topic. I went to his Tuesday
To a statistician, the LAG 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 provides a convenient way to compute quantitites that involve adjacent values in any vector. The LAG function is essentially a "shift operator."
Getting the axis values just right generally requires some work, and the values you want can change from case to case. One such example was discussed by Dan Heath in his post on custom axis values. Here Dan shows the usage of non uniform axis values using the VALUES option on
Question: What do John Travolta, Gina Davis, and I all have in common? (I mean, besides the obvious fact that we are all awesome dancers.) Answer: We have all had makeup applied by artist Roxie Stice. I was the host for two SAS Tech Talks, which were broadcast via Livestream
In some weird twist of fate, I have gone from being anti-social media to blogging on SAS Canada and now to blogging on the SAS Users Groups blog. Crazy world! A little about myself first: I am married, been using SAS for about a year and a half, work for
