The farther you try to forecast into the future, the less certain you are -- how can you represent that graphically? One way is to draw a shaded/colored "confidence interval" around your forecast line, but this is something a lot of SAS users have trouble with. That's why I decided to create
Being so close before Christmas I thought it would be a good idea to see what route Santa Claus is planning this year. Not just because I'm living in Australia and Santa usually comes in t-shirts & shorts but also because it's a long way to get down here. So
We want to extend a huge thank you to everyone who donated their leftover (and excess) Halloween candy this year, you outdid yourselves!! We tipped the scales at more than 220 pounds of candy- 65 more pounds than we collected last year! Wondering what happened to all that Halloween candy?
This is the time of year when we like to make predictions about the upcoming year. Although I am optimistic about the potential of predictive analytics in the era of big data, I am also realistic about the nature of predictability regardless of how much data is used. For example, in
Creating a Bar Chart with a table of statistical data aligned with the bars is a popular topic. With SAS 9.4, creating such graphs gets easier with the new AXISTABLE statement in GTL and SG procedures. But some use cases can flummox the latest gizmos. Such is the case I ran into recently. Here
Recently a SAS/IML programmer asked a question regarding how to perform matrix arithmetic when some of the data are in vectors and other are in matrices. The programmer wanted to add the following matrices: The problem was that the numbers in the first two matrices were stored in vectors. The
Zur Jahreswende fragt man sich: Welche Themen waren 2013 wichtig und kommen wahrscheinlich wohl 2014 wieder auf den Tisch? Da denke ich doch an: Compliance. Also die Fähigkeit eines Unternehmens und der Mitarbeiter, Gesetze und Vorschriften zu kennen und einzuhalten, interne Vorgaben zu definieren, zu implementieren und gleichzeitig auch deren
Data on punched-cards, SAS software delivered on tape, jobs in the queue on the mainframe, printouts on green-bar paper ... we really appreciate all our SAS users, but if any of the above are part of your "SAS memories" we especially appreciate you! I guess I'm a computer geek, because
Last week I covered some of the interesting graph-related papers presented at WUSS. There were quite a few, so I broke up the report into two parts. Here is the second installment. In the paper Creating Graphical Patient Profiles using SAS by William Garner of Gilead Sciences, the author describes how to create
Pomegranates are popping up everywhere and are in everything from ice cream and rice cakes to body wash and even candles! So what’s the big deal about pomegranates?
When learning a new language, it is important to learn to interpret error messages that come from the language's parser or compiler. Three years ago I blogged about how to interpret SAS/IML error messages. However, many questions have been posted to the SAS/IML Support Community that indicate that some people
It is always a pleasure to attend SAS user conferences, regional conferences and in-house events. In addition to presenting papers, seminars and super demos to the attendees myself, my favorite activity is to attend presentations by users that include graphical data visualization. These include using SG procedures, GTL, Designer or SAS/GRAPH. This year
Each year my siblings choose names for a Christmas gift exchange. It is not unusual for a sibling to pick her own name, whereupon the name is replaced into the hat and a new name is drawn. In fact, that "glitch" in the drawing process was a motivation for me
As the “Year of Statistics” comes to a close, I write this blog in support of the many statisticians who carefully fulfil their analysis tasks day by day, and to defend what may appear to be demanding behavior when it comes to data requirements. How do statisticians get this reputation? Are we
There are 2 kinds of people in the world -- those who dread change, and those who look forward to it. Which kind of person are you, when it comes to upgrading your SAS software?!? With most software (such as Windows OS, Facebook, Gmail, etc) I tend to fall into
