It is often useful to partition observations for a continuous variable into a small number of intervals, called bins. This familiar process occurs every time that you create a histogram, such as the one on the left. In SAS you can create this histogram by calling the UNIVARIATE procedure. Optionally,
Last week, I presented some highlights of the new features for SG Procedures and GTL in SAS 9.4. Now, let us dig in a bit deeper. For a plot without a GROUP role, setting an attributes was always easy with SG procedures. All you need to do to set bar color
Did you know that more than 30,000 Americans die in traffic accidents every year? Interestingly, the U.S. import of mangoes from Brazil is found to be highly correlated with this fatality rate, as shown in the graph below. But are mango imports a good indicator of the future traffic fatality
This week's SAS tip is from Lauren Haworth, Cynthia L. Zender, and Michele Burlew's book Output Delivery System: The Basics and Beyond. This example-driven book includes broad coverage of some of the best features of ODS. To learn more about the book and the authors, visit our Web catalog to read
To say that I'm excited about the SAS 9.4 release is an understatement! For example, did you know that in SAS 9.4, you can write SAS/Graph output directly to a Powerpoint slide?!? This is definitely an item that was on my "wish list," and will no doubt make life a
SAS 9.4 releases today with a ton of new features. As eloquently stated by Craig Rubendall, the driving themes are "Enable. Simplify. Innovate". The same sentiment applies to the ODS Graphics, with a ton of new features for the SG Procedures, GTL and ODS Graphics Designer. In the next few articles,
I don’t think people typically think of administration as a fun thing, but it really was fun talking to SAS administrators at SAS Global Forum this year. There seemed to always be a crowd around the administration demo station. We had quite a few super demos and papers, and we
Most of us will have at least a few road trips this summer (some longer than others). Traveling in the car doesn’t mean you have to give up your healthy habits. It just takes a little planning.
Are you still using the old RANUNI, RANNOR, RANBIN, and other "RANXXX" functions to generate random numbers in SAS? If so, here are six reasons why you should switch from these older (1970s) algorithms to the newer (late 1990s) Mersenne-Twister algorithm, which is implemented in the RAND function. The newer
SAS 9.3 already has smooth (anti-aliased) lines in SAS/GRAPH device=png output, and in SAS 9.4 you will also get smooth lines in your device=gif output (and gif animations)! Woo-hoo!!! Here are a couple of simple examples to demonstrate: The first example is device=gif Proc Gmap output. If you look very closely, you'll notice that
The DELETE procedure is probably the most well-known and most-used SAS procedure that isn't actually documented or officially supported. That is, that was the case before the release of SAS 9.4, when PROC DELETE returns with more features than ever -- including a production-quality status. In his SAS Global Forum
Tried, tested and true -- I’m sure you already practice some, if not all, of these efficient techniques to save resources. I recently shared these 10 techniques with the Wisconsin Illinois SAS users group in Milwaukee. The conference ran smoothly under the incredibly able guidance of Dr. LeRoy Bessler. I’ll
Four authors. Four papers. One set of data. The month of August and the 2014 Call for Content are just around the corner, and this seems like a good time to share a little inspiration and innovation. The Foundations and Fundamentals paper section at SAS Global Forum 2013 featured a four-part
Every programming language has an IF-THEN statement that branches according to whether a Boolean expression is true or false. In SAS, the IF-THEN (or IF-THEN/ELSE) statement evaluates an expression and braches according to whether the expression is nonzero (true) or zero (false). The basic syntax is if numeric-expression then do-computation;
Conventional or Organic? That is the question. Research varies about whether organic foods are healthier than conventional foods. However, one of the biggest arguments for buying organic is in regards to pesticide exposure. Convincing evidence is revealing that the pesticides we eat, drink and inhale are stored in our bodies
