In Part 1, we reviewed 3 nutrients that help stabilize moods: Folate, Omega 3 Fatty Acids and L-Theanine. Read further to learn 3 additional nutrients that have a positive impact on our moods and energy levels. 4. MAGNESIUM Magnesium is crucial for more than 300 body functions including anti-anxiety benefits.
My last blog post described three ways to add a smoothing spline to a scatter plot in SAS. I ended the post with a cautionary note: From a statistical point of view, the smoothing spline is less than ideal because the smoothing parameter must be chosen manually by the user.
Having served as conference chair for last year’s SAS Global Forum, I am so looking forward to just being a normal attendee at this year’s conference in Washington, DC. That’s right, I’ll have no speaking commitments, no interviewers, no responsibilities—just the privilege of selecting the content that is right for
Networking with other SAS users is what I love most about SAS Global Forum! At every conference, I look for ways to find those who share my interests or whose experience sheds new light on my use of SAS software. When I come across tips on networking, I always try
Like many SAS programmers, I use the Statistical Graphics (SG) procedures to graph my data in SAS. To me, the SGPLOT and SGRENDER procedures are powerful, easy to use, and produce fabulous ODS graphics. I was therefore surprised when a SAS customer told me that he continues to use the
Classification panels are a very popular visual representation of the data, where the data is gridded by class variables all in one graph. This makes it easy to compare and contrast the data by these class variables. The SGPANEL procedure makes this easy, and most of the time it is
IT support levels for different processes and business applications depend on many factors. So how are analytics projects generally supported? It's common for IT to view the implementation of advanced analytics as part of a production job or process, especially when analytic models are deployed into different operational systems that are
SAS administrators now have another tool to keep SAS users from straying off their permitted path: the LOCKDOWN system option. The option was introduced in "stealth mode" for SAS 9.4. In SAS 9.4M1, it became a true, documented option. For the official guide to creating "locked-down servers", see the SAS
Most SAS programmers would agree that they use the SET statement without giving much thought to the syntax, because it’s such a widely used statement of choice. We routinely name the expected data sets and possibly a few options, and away we go. A visit to the documentation can be
People who know me know that there’s one thing I hate at work – duplication of efforts. I’m not talking about working on a problem in a coordinated fashion. I’m talking about two or more people doing the same work, to answer the same question. Without coordination, there will be
In this interconnected world, it is more important than ever to understand not just details about your data, but also how its different parts are related to each other. Social networks reveal often surprising details about what people think about your product or services, how they are linked to other
SAS Environment Manager 2.1 (which was released with SAS 9.4 M1), has new features to make it easier to manage your SAS environment. For example, it now supports metadata clusters, and it has an improved method for handling access to the application. But the biggest change is in metadata access.
My previous post described how to use the "missing response trick" to score a regression model. As I said in that article, there are other ways to score a regression model. This article describes using the SCORE procedure, a SCORE statement, the relatively new PLM procedure, and the CODE statement.
I had the opportunity to moderate a roundtable discussion on risk management at the International Institute for Analytics’ (IIA) winter symposium in Orlando earlier this month. I set the stage for the session with a brief overview of my favorite risk approach, “Competing on Value”, by Mack Hannan and Peter
When the Apple Macintosh hit the market, analysts were not impressed. But Steve Jobs’ vision ended up transforming our lives. Apple is celebrating its 30th anniversary this year and has become a global household name. Jobs’ ability to direct his organization to develop easy to use products not only met
Teacher pay, and the possibility of a raise, has been a hot topic in North Carolina lately. So I decided to look around and see if I could find any good data related to teacher salary, and then try to determine the best way to present that data graphically. I found that
Last week’s Winter Storm Pax closed schools, businesses and government here in the eastern US. Perhaps we were inspired by warm thoughts of America’s capital city in the spring. Perhaps spending so many days at home alone underscored the value of sharing information and insights with coworkers. Or, perhaps after
Last week's SAS Talks session, My Favorite SAS Enterprise Guide 5.1 Tricks, was remarkable in several ways. First, the featured presenter was Marje Fecht, who also serves as the conference chair for SAS Global Forum 2014. She's an avid SAS professional who loves to educate her fellow SAS users on
A fundamental operation in statistical data analysis is to fit a statistical regression model on one set of data and then evaluate the model on another set of data. The act of evaluating the model on the second set of data is called scoring. One of first "tricks" that I
Browsing graphs on the web, this graph caught my eye: The Arctic Sea Ice Volume Graph. My interest is not so much in the debate on Climate Change or Global Warming. To me, this graph has some interesting features that can help show the benefits of plot layering to
I was recently part of team discussing enterprise architecture with a chief IT architect, and we were explaining how SAS can integrate into their existing infrastructure, add business value on top it and even fit into their future planned infrastructure. This conversation was one of the reasons I blogged about
The attention of the world is now on Sochi and the Winter Games. Gold, Silver and Bronze medals are being earned by these amazing athletes, and everyone has an eye on the tally. Andre sent me a link to TRinker's R Blog, showing a graph of the current tally. Andre
Valentine’s Day is one of those make-or-break holidays for gift retailers. They are selling "nice to have" items, not necessities. Many use some type of analytics to segment customers for personalized messages. It's not as straightforward as it sounds, especially if the organization hasn't committed to an enterprise-wide approach to
Here in the SAS Performance Lab, we’re seeing more and more SAS sites moving their SAS® 9 application workloads to Windows Server 2012. Now that we’ve had sufficient time to gather feedback from early implementers of SAS on these systems, we thought you might want a recap of some of
No doubt many folks feel an energy slump in the winter months. Short days and long nights plus the added drain of gray or rainy days can dampen our spirits. Did you know certain nutrients may help calm anxiety or boost your spirits? If you feel a drop in your
Although I currently work as a statistician, my original training was in mathematics. In many mathematical fields there is a result that is so profound that it earns the name "The Fundamental Theorem of [Topic Area]." A fundamental theorem is a deep (often surprising) result that connects two or more
It's true: you can use the Microsoft Visual Studio Express tools to build custom tasks for SAS Enterprise Guide and the SAS Add-In for Microsoft Office. And I said as much in my book, Custom Tasks for SAS Enterprise Guide Using Microsoft .NET. I even provided step-by-step instructions for how
Hopefully, you’ve listened to SAS Global Forum 2014 Conference Chair Marje Fecht talk about the focus on content at this year’s conference. The Conference Scheduler is central to achieving that goal, helping you easily find and schedule the presentations, tutorials and activities that meet your needs and interests. In this
One of my favorite new features of SAS/IML 12.1 enables you to define functions that contain default values for parameters. This is extremely useful when you want to write a function that has optional arguments. Example: Centering a data vector It is simple to specify a SAS/IML module with a
One of the most popular graph amongst clinical and pharmaceutical users is the Survival Plot as created from the LIFETEST Procedure. This is one graph that users most often want to customize. See Creating and Customizing the Kaplan-Meier Survival Plot in PROC LIFETEST - Warren F. Kuhfeld and Ying So, SAS Institute
