My first trip to Portland, Maine, gave me more than I had expected - it was a touching, heartwarming experience that was not what I thought I'd signed up for. Let me explain: While planning my flight and other travel arrangements, I realized that I would arrive in Portland early
Earlier today, Rick posted interesting information about which time of year the most babies are born, at least in the USA. I don't have data nearly as extensive as what's available at the NCHS, but I do have a sample of birthday records to compare against Rick's findings. My sample
Do you know someone who has a birthday in mid-September? Odds are that you do: the middle of September is when most US babies are born, according to data obtained from the National Center for Health Statistics (NCHS) Web site (see Table 1-16). There's an easy way to remember this
Did you know that the Pacific Northwest SAS® Users Group (PNWSUG) is the oldest regional SAS users group in the U S, offering conferences since 1981? This year PNWSUG updated their usual multi-day, one location conference. They'll offer two convenient one-day conferences: one on September 19 in Seattle and one September
I use Google Reader to keep up with SAS-related conversations on the blogosphere. I thought it would be nice to share the lists of blogs that I follow as "shared bundles". If you also use Google Reader, it will be very easy for you to add these bundles to
‘Context’ defined (as cited from the Merriam-Webster Online Dictionary): 1: the parts of a discourse that surround a word or passage and can throw light on its meaning; and, 2: the interrelated conditions in which something exists or occurs: environment, setting. While context is clearly important, today it is consistently
Looping is essential to statistical programming. Whether you need to iterate over parameters in an algorithm or indices in an array, a loop is often one of the first programming constructs that a beginning programmer learns. Today is the first anniversary of this blog, which is named The DO Loop,
In Part 1, Udo provided SAS code to replicate the example in Hyndman's blog. Below, he shows the results of out-of-sample testing, and draws some conclusions on the computational efficiency of this approach. Out-of-sample Testing In addition to the example shared by Hyndman, out-of-sample data was used to illustrate the final performance
We ship many sample data sets with SAS products. By using well-understood sample data sets, we can teach concepts or show off product features without distracting the audience/students with data collection or prep. At least, that's the way it's supposed to work. But occasionally the sample data can cause a
In this guest blogger post, Udo Sglavo of the Advanced Analytics Division of SAS shows how to conduct time series cross-validation using SAS Forecast Server. Udo replicates the example from Rob J Hyndman's Research Tips blog. Replicating the Example In order to replicate the example in Hyndman's blog, the example
My elderly mother enjoys playing Scrabble®. The only problem is that my father and most of my siblings won't play with her because she beats them all the time! Consequently, my mother is always excited when I visit because I'll play a few Scrabble games with her. During a recent
Academic Chair Barbara Okerson and Operations Team Lead Marje Fecht are chairing the 2011 SouthEast SAS Users Group (SESUG) conference. This year's conference will be held in another wonderful historical city slightly north of the 2010 Savannah location; it'll be located in Alexandria, Virginia, October 23 - 25. The format
It's been a well-known limitation for a long time. When you connect to a SAS session using SAS Enterprise Guide, shell commands (including X command, SYSTASK, and FILENAME PIPE) are off-limits because the default SAS invocation disables them. It does this by including -NOXCMD as a command-line option. This makes
Hurricane Irene impacted 20% of the US population and will cost billions in recovery dollars. Now that the water has begun to subside, the real long term work begins. And it is this work that can be another disaster, or, a real economic benefit to a state. How so? FEMA
The hurricane didn't get me, but Monday night's thunderstorm sure played a dirty trick. After leaving my car windows cracked open over night, I drove to work Tuesday morning feeling a little soggier by the minute. Upon arrival at SAS, I was aghast to find the seat of my pants was soaked
I recently attended the Medicaid Management Information System (MMIS) Conference in Austin, Texas. The MMIS conference is an annual event for federal and state HHS agencies to share programmatic and technology initiatives in Medicaid and Children’s Health Insurance Programs (CHIP). While I have attended numerous MMIS conferences in the past, I
I previously showed how to generate random numbers in SAS by using the RAND function in the DATA step or by using the RANDGEN subroutine in SAS/IML software. These functions generate a stream of random numbers. (In statistics, the random numbers are usually a sample from a distribution such as
At least, that's according to my colleague, Rick Wicklin. In a recent blog post, Rick points out that estimating popularity based on results of Google searches is a bad idea. Well, that just disqualified my claim that PROC REPORT is more popular than PROC TABULATE, as measured via a GoogleFight.
While talking to SAS users in Australia earlier this month, I often demonstrated the capabilities of the new Map Chart task in SAS Enterprise Guide 4.3. Creating map charts has never been easier: select your map data source, then select your response data source, and click Run. Voila! You've got
Was the SAS Insight Series in New Zealand and Australia a prelude to the Rugby World Cup? Perhaps it was, even if you cannot find it on the list of official events. But consider these coincidences: Like the Rugby World Cup, my trip was also sponsored by MasterCard. (Okay...not
One of the highly visible changes in SAS 9.3 is the fact that the old LISTING destination is no longer the default destination for ODS output. Instead, the HTML destination is the default. One positive consequence of this is that ODS graphics and tables are interlaced in the output. Another
Exploring correlation between variables is an important part of exploratory data analysis. Before you start to model data, it is a good idea to visualize how variables related to one another. Zach Mayer, on his Modern Toolmaking blog, posted code that shows how to display and visualize correlations in R.
Contributed by Rex Pruitt, IFSUG Chairman ~ During SAS Global Forum 2011 in Las Vegas, a small group of users gathered to organize the first IFSUG (Insurance and Finance SAS Users Group). Today, there are more than 370 enrollees in IFSUG Constant Contact, 60 members in the IFSUG LinkedIn group
We had a tornado in April, an earthquake on Tuesday, a drought all summer, and a hurricane arrives on Saturday. All I can figure is that Cary, NC has way too many sinners per capita. What's next -- pestilence? The BFD Makeover The BFD (and all SAS blogs) will now be
The recent budget debate between President Obama and Congress reminded me of many of the discussions I observed during my years as State Controller and Deputy State Budget Officer in North Carolina. These discussions are related specifically to principles adhered to in budget development and budget deliberations by elected officials.
Rick Langston from SAS will be the keynote speaker for MWSUG 2011 (MidWest SAS Users Group) . Watch his short video for highlights of some of the great reasons to schedule your trip to Kansas City, Kansas, September 25 - 27.
You can generate a set of random numbers in SAS that are uniformly distributed by using the RAND function in the DATA step or by using the RANDGEN subroutine in SAS/IML software. (These same functions also generate random numbers from other common distributions such as binomial and normal.) The syntax
The highway system traversing the United States quietly hit a milestone last month with the 55th anniversary of the Federal Aid Highway Act. In 1956 President Eisenhower had a vision for our nation’s infrastructure; he knew that building an interstate highway system was vital, and expressed that “Together, the united
Registration is now open for the SCSUG 2011 (South Central SAS Users Group) educational forum to be held at the Sheraton Fort Worth Hotel and Spa in Fort Worth, Texas November 6 - 8. Whet your SAS tastebuds with this lineup of speakers: Keynote Address What’s New in SAS® 9.3 Rick Langston
NOTE: SAS stopped shipping the SAS/IML Studio interface in 2018. It is no longer supported, so this article is no longer relevant. When I write SAS/IML programs, I usually do my development in the SAS/IML Studio environment. Why? There are many reasons, but the one that I will discuss today
