You can still get a paper proposal in for SAS Global Forum 2012. All you need is an idea. And probably some data. And also, some techniques for analyzing that data. Oh, and some conclusions would be helpful as well. I know: you are a busy person! You might not
~Contributed by Martin L. Olesen I began using SAS 6.04 in 1992 for my own projects and as a teaching assistant. Professionally, I have worked in SAS since 1997, after graduation. I use Base SAS, SAS/STAT and SAS/OR. I work in an Icelandic bank doing credit risk analysis and rating
Sometimes you want to label only certain observations in a plot. This is useful in many ways, but one use is to label outliers on a scatter plot. In the SGPLOT procedure, the DATALABEL= option enables you to specify the name of a variable that is used to label observations.
Often we have the need to display multiple columns of data in a graph, and we want to introduce some separation into their placement in the graph. Or, we want to display a bar chart of multiple response variables, and place the values side-by-side, like in a grouped bar chart. For both
The popular mailing list for the SAS user community hits a milestone this weekend by turning 25. 25 is often referred to as the "silver anniversary", but for a quarter century SAS users have found gold among the messages in this list, which feature everything from questions and answers about
Drill-through to detail is the ability to right click within a cell of a web report or OLAP viewer and request the detail source records that make up that specific cell's measure. The maximum number of records, by default, is set to 300,000. Feasibly the report user could download all
Winter is still 6 weeks away, but already parts of the US are under feet, that’s right FEET, of snow. All of the reports I have read say that there is no correlation between this early activity and how brutal the winter will be. I wonder if there is any
I was at the Wikipedia site the other day, looking up properties of the Chi-square distribution. I noticed that the formula for the median of the chi-square distribution with d degrees of freedom is given as ≈ d(1-2/(9d))3. However, there is no mention of how well this formula approximates the
Celebrity fame (I'm told) is overrated. Do you really want hordes of people to recognize you in the shopping mall or while you wait at a red light? Of course you don't. And that's why I advise you to never win the American Idol competition (nor should you lose with
JSM, Miami Beach, FL, July 31–August 3 Miami Beach in August is hot. Ridiculously hot. Almost as hot as our preview copies at this show. Conference goers were extremely excited about a number of our upcoming statistics titles, including Customer Segmentation and Clustering Using SAS® Enterprise Miner™, Second Edition, by
What do you call an interview on Twitter? A Tw-interview? A Twitter-view? Regardless of what you call it, I'm going to be involved in a "live chat" on Twitter this coming Thursday, 10NOV2011, 1:30–2:00pm ET. The hashtag is #saspress. Shelly Goodin (@SASPublishing) and SAS Press author recruiter Shelley Sessoms (@SSessoms)
In a production environment, where dozens of SAS programs are run in sequence, often monthly or quarterly, and where logs can span thousands of lines, it’s easy to overlook the small stuff that can cause data hangovers. Recognize any of these? A temporary data set finds its way into subsequent
Last week I showed how to use the UNIQUE-LOC technique to iterate over categories in a SAS/IML program. The observant reader might have noticed that the algorithm, although general, could be made more efficient if the data are sorted by categories. The UNIQUEBY Technique Suppose that you want to compute
Welcome to this new blog on data visualization at SAS. Our goal is to engage with you on a discussion about analytical and business graphics for reporting and interactive applications. Our primary focus will be on ODS Graphics and related topics, but we look forward to a lively discussion on all things
On September 10, 2001, I was attending a law enforcement conference in Atlantic City, NJ. While I have attended hundreds of similar meetings, this conference stands out for several reasons. First, and most obvious, it was the eve of the day where most of our lives were indelibly altered. Second,
Now this is the way you sports fans should be thinking of using SAS! Of course there are no real specifics here, but you guys are pretty smart. Here's an older story about using SAS for sports, and I'm sure you've all seen Money Ball by now. Today's series entrant is
Being able to reshape data is a useful skill in data analysis. Most of the time you can use the TRANSPOSE procedure or the SAS DATA step to reshape your data. But the SAS/IML language can be handy, too. I only use PROC TRANSPOSE a few times per year, so
Howdy. This is Andrew T. (Andy) Kuligowski, the SAS Global Forum 2012 Conference Chair. I’ve been using SAS® for more than 20 years – OK, a LOT more than 20 – and attended my first SAS Global Forum (then called SUGI, SAS Users Groups International) in Dallas, Texas back in
This blog post is a "mashup" of a couple of my previous posts, combining the lessons to create something brand new that I hope you will find useful. First, let's review what we know: SAS Enterprise Guide supports a scriptable object model, which allows you to write scripts or programs
I was recently asked the following question: I am using bootstrap simulations to compute critical values for a statistical test. Suppose I have test statistic for which I want a p-value. How do I compute this? The answer to this question doesn't require knowing anything about bootstrap methods. An equivalent
When you analyze data, you will occasionally have to deal with categorical variables. The typical situation is that you want to repeat an analysis or computation for each level (category) of a categorical variable. For example, you might want to analyze males separately from females. Unlike most other SAS procedures,
We'll interrupt the series on Why Forecasts are Wrong, with a report from the inaugural Analytics 2011 conference, held last week in Orlando. A2011 drew over 1025 attendees (from 44 states and over 25 counties). The Analytics conference series features a wide range of topics (including forecasting, optimization, data mining, text
One great element of SAS’ Analytics2011 conference (not a SAS Users Group conference, but a great place for SAS users to find information about using SAS) is how it gives students a platform to showcase their work in analytics. Every year, hundreds of posters are submitted outlining innovative applications and research
In SAS/IML 9.22 and beyond, you can call the R statistical programming language from within a SAS/IML program. The syntax is similar to the syntax for calling SAS from SAS/IML: You use a SUBMIT statement, but add the R option: SUBMIT / R. All statements in the program between the
Writing is usually very easy for me - I close the door and concentrate on the task at hand. But today, my mind is wandering. Maybe it's the changing season (it's fall in the US) that makes me think of all of the SAS users who might be reading my posts:
"I think that my data are exponentially distributed, but how can I check?" I get asked that question a lot. Well, not specifically that question. Sometimes the question is about the normal, lognormal, or gamma distribution. A related question is "Which distribution does my data have," which was recently discussed
Years ago and a seemingly far galaxy away, I wrote about how to modify 9.1.3 to start Enterprise Guide users in a different location for the File folder. By default, the user only can access their personal SAS Temporary File. Why change this? I would prefer to use a central
I was contacted by SAS Technical Support regarding a customer who was trying to use SAS/IML to compute quantiles of the folded normal distribution. I had heard of the distribution, but it is not built into SAS and I had never worked with it. Nevertheless, I set out to understand
For the past year, I’ve had the pleasure of serving on the communications team of the National Collaborative for Bio-Preparedness (NCB-P), of which SAS is a partner and the analytics provider. That experience was heavy on my mind as I recently watched the film Contagion. I may drop some minor
“I really wish someone had shown me this function in SAS sooner, because it’s saved me a ton of time and effort,” said Brandi Rhoads as she opened her presentation at the Western Users of SAS Software (WUSS) conference in San Francisco.
