They say "Imitation is the most sincere form of flattery"... Therefore when I imitate Hans Rosling's famous world-data animation, it's not that I'm jealous, but that I'm paying homage to him! (OK, and maybe also a little bit jealous! LOL) Well, anyway, for those of you who haven't seen it,

Reading Jan Bigalke’s SAS Global Forum paper on “Hardening a SAS® Installation on a multi tier installation on Linux" reminded me of baking apple stack cake with my mother. Neither is a simple project. Both are time-consuming, and their success depends on how skillfully you handle each layer. Data security

The power of a statistical test measures the test's ability to detect a specific alternate hypothesis. For example, educational researchers might want to compare the mean scores of boys and girls on a standardized test. They plan to use the well-known two-sample t test. The null hypothesis is that the

Meine Oma sagte mal zu mir: „Gut dass du Jura studierst, das ist ein Beruf mit Zukunft. Denn betrogen wird immer.“ Zwar hatte ich zu diesem Zeitpunkt noch gar keine Entscheidung über meinen beruflichen Weg getroffen, der Satz selbst allerdings blieb mir im Gedächtnis. In all den Jahren hat sich

At SAS, one of our core values is to be swift and agile. So it makes sense that our software development be Agile too. The Agile methodology has been around for more than 10 years and was designed with software development in mind. Today, it is still used predominately for
Often we want to visualize the relationship between variables over time. The understanding of such data can be improved by viewing the animated graph over time. With SAS 9.4, you can create animated graphs using the new animation options on the OPTIONS statement and the PRINTER destination. A popular example an

I recently read an interesting article in The Economist, where they describe "The Big Mac index." This is an index they invented as a lighthearted guide to compare currencies in different countries. In their article they create a multi-panel display (similar to a dashboard) where they compare the index for several countries using

A good chunk of the SAS year revolves around SAS Global Forum. Pre-conference, everyone is busy polishing presentations and planning meetings. Post-conference is the best—attendees come back to Cary with heads full of customer ideas to implement and notebooks full of contacts to follow up on. One user's request found its

Humans have over 10,000 taste buds which are made up of hundreds of receptor cells that control our sense of taste. Each type of receptor responds to one of these 5 basic tastes: Sweet: activated by presence of sugars (ie: fruit, sugary drinks, desserts) Salty: activated by presence sodium chloride

"And the winner is…" Ob der Branchen-Oskar für wirksame Marktkommunikationen, der "GWA Effie", oder die "Löwen von Cannes" für inspirierende Kreativität: Im Frühsommer ist es traditionell wieder an der Zeit, Preise zu verleihen* in der Marketing- und Werbebranche! Sicher: Kreative Leistungen und erfolgreiche Zielgruppenansprachen in klassischen Medien, im Online-Bereich oder im

Last week I alluded to some very useful applications of the Copy Files task. This is one of them. If you have SAS Enterprise Guide 7.13 or later, the Copy Files task is in the Tasks->Data menu. In earlier versions, you'll have to download/install the task as a custom task.

Every time you see a rainbow, do you look to see where it begins and where it ends? Legend has it that there is a pot of gold at the end of each rainbow with leprechauns guarding it. While this might be popular Irish folklore, and you may not find

For programmers who are learning the SAS/IML language, it is sometimes confusing that there are two kinds of multiplication operators, whereas in the SAS DATA step there is only scalar multiplication. This article describes the multiplication operators in the SAS/IML language and how to use them to perform common tasks

Recent versions of SAS Enterprise Guide (version 5.1 and later) use Microsoft .NET 4.0, which enforces additional security requirements before running custom task DLLs that you download from the Web, including those that you download from support.sas.com. Because these task DLLs are downloaded from the (big and scary) Internet, the

Students with missing test scores are often highly mobile students and are more likely to be low-achieving students. It is important to include these students in any growth/value-added model to avoid selection bias, which could provide misleading growth estimates to districts, schools and teachers that serve higher populations of these
