A little-known but useful feature of SAS/IML 12.3 (which was released with SAS 9.4) is the ability to generate a vector of lowercase or uppercase letters by using the colon operator (:). Many SAS/IML programmers use the colon operator to generate a vector of sequential integers: proc iml; x =
So far in our Ask the Statistician blog and video series, we have heard responses from statisticians at the Analytics 2013 conference about: The many ways statistics benefit their organizations. The types of statistical analyses used to solve business issues. Best practices for explaining results. How they put statistical
I’ve recently had the opportunity to learn a little more about administering SAS Visual Analytics. The sessions introduced me to two new GUI interfaces that simplify the work for SAS administrators. In my last post, I shared how to load data into memory using the SAS Visual Data Builder. After
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

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.
