Do you ever look at a chart or graph and think about what it’s really trying to reveal? All the time, right? Visualizations are useful because they allow us to analyze information much quicker than if we were to look at the raw data by itself. I say this with
Principle 7: Accuracy - Risk management reports should accurately and precisely convey aggregated risk data and reflect risk in an exact manner. Reports should be reconciled and validated. Successful demonstration of Principle 7 requires senior management to rely upon the information presented in risk reporting. Since forward-looking strategic decisions are
Data federation is a relatively new term used to describe a form of data virtualization. Data virtualization, however, is not new. It has been around since at least the 1960's when virtual memory was introduced to simulate additional memory beyond what was physically available on a machine. While data federation is a

Vielleicht lag es daran, dass mein Opa Automechaniker war und ich schon als 3-Jähriger wusste, was ein 17er Schlüssel ist. Vielleicht ist
Imagine this scenario: Every device we encounter in our day-to-day routine – from our refrigerators and automobiles to our water and gas meters – has embedded sensors that read real-time information and generate unfathomable amounts of data. Now take this scenario one step further. Imagine what kinds of insights we’d
A recent Charlotte Observer article provided a thoughtful investigation of growth and achievement in North Carolina’s Charlotte Mecklenburg Schools). The article juxtaposed two very different, yet highly effective, schools. The first, Ranson Middle School, is a low-achieving school with 84% poverty that demonstrated the highest academic growth of any similar
In light of the recent reports that glaciers in Antarctica are melting, what SAS graphs might be useful in analyzing the data?... When floating sea ice melts (such as at the North Pole), it doesn't raise the sea level - but when ice on land melts (such as glaciers at
SAS administrators often ask for a utility that can detect orphaned SAS WORK and SAS Utility directories on their back-end SAS compute systems. These orphaned directories result when a SAS Enterprise Guide or any other SAS GUI application is terminated incorrectly, and the SAS session does not terminate properly. SAS
There has been lots of awareness-raising lately about the safety of our food supply including the tools we use to cook and store our food. Many nutritionists, health care providers and scientists agree that reducing exposure to toxins whenever possible makes good sense. The Environmental Working Group (EWG), an environmental
Last week, as part of an article on how spammers generate comments for blogs, I showed how to generate random messages by using the CATX function in the DATA step. In that example, the strings were scalar quantities, but you can also concatenate vectors of strings in the SAS/IML language.
What if you could rank where you stand versus your industry peers when it comes to how effectively you're making use of your data through analytics? Now you can. Jim Davis, Senior Vice President and Chief Marketing Officer at SAS, outlined an eight-metric test at today’s Premier Business Leadership Series
The US health care industry is always getting a bad rap. It takes heat for being too expensive or not efficient enough or just too complicated. We know we need it, and that living long and healthy lives requires it. But we also know we love to complain about it
This SAS tutorial video will show you how to generate plots for two continuous numeric variables with Base SAS. Basic scatter plots, linear or curvilinear regression lines, confidence intervals or ellipses, and multiple plot overlays are demonstrated. To learn more about this topic, check out our SAS Programming 1: Essentials
It was just a couple of years ago that folks were skeptical about the term "data scientist". It seemed like a simple re-branding of an established job role that carried titles such as "business analyst", "data manager", or "reporting specialist". But today, it seems that the definition of the "Data
In my recent post on how to understand character vectors in SAS/IML, I left out an important topic: How can you allocate a character vector of a specified length? In this article, "length" means the maximum number of characters in an element, not the number of elements in a vector.
