A collegue who works with time series sent me the following code snippet. He said that the calculation was overflowing and wanted to know if this was a bug in SAS: data A(drop=m); call streaminit(12345); m = 2; x = 0; do i = 1 to 5000; x = m*x

When the IASUG conference founder and 2012 co-chair John Xu was asked what makes this one-day event so successful year after year, he said, “The most important factor is the leadership. We are lucky that we have core conference volunteers committed to supporting the conference.”
Last Friday morning I took a meeting with SAS CEO Jim Goodnight. Despite the hassle, I was happy to rearrange my busy schedule to squeeze him in. Ha! Just a little joke there about my inflated sense of importance! Actually, the meeting was part of a regular series called "Conversations
A common question really and one that I get after posting code like yesterday's All SAS Stored Process Locations Report. The neat trick is just to type METABROWSE in a BASE SAS command window. (There are two other commands: METACON and METAFIND. Has anyone got any tips on when those
Stored process code can exist within the metadata itself for version 9.3 (the benefits of which I discussed earlier). But for all other versions (and as a option in version 9.3) the SAS code is stored as a .sas file within the server's file system (or mapped folder/drive structure). When editing
CTSPedia.org is a website of Knowledge Base for Clinical and Translational Research. On this site you can find sample graphs for statistical analysis of safety data for Clinical Research. Graphs included in this resource have been submitted by contributors, and include a graph for Liver Function for different tests by treatment.
In this Flipcam video by SAS' Steve Polilli, Don Kros and Jon Boase discuss the methodology they developed to help SAS users in their organization advance their SAS skills. Kros and Boase submitted a poster, which you'll see in the video, and a paper "The Path to Developing Your Organization's SAS Skills,"
SAS and SAS users have a great history of collaborating to build and improve SAS software. Soon, that history will be repeated (on a grander scale!) with the development of the SAS Leadership Council.
The date prompt from SAS Prompt Framework provides the options of single selection or a range, however what if you need to select multiple individual dates such as Monday (May 28), Wednesday (May 30), and Friday (June 1) of last week? There are a few alternatives to accomplishing this. Option
If you are like many SAS Enterprise Guide users, you've amassed a large collection of project files (EGP files) that contain important content: programs, logs, notes, results, and more. However, to most tools and processes, the EGP file is opaque. That is, you can't see what's inside of it unless
A graph in a recent article in Fortune magazine caught my eye. The graph shows the cost of hosting the Summer Olympics over the past eight events. Here is what I termed the "Medal" graph. Now, practitioners of the art of Effective Graphics would likely find some shortcomings in the graph. Clearly
Did you change your LinkedIn password yesterday? (If you didn’t, you should!) But did it happen to be the same as your corporate password? First, tisk tisk. Second, change your corporate password NOW! Ok, now that this is done ~ don’t let your saved connection profile for SAS applications lock
It’s going to be a busy summer with a lot of travel. I’ve been invited to several user conferences so I’m really excited to get to meet even more SAS users, pick up some great tips for others, and wear myself out chatting.
What if you would like to make a copy of an existing stored process to test out your changes before making them live? The copy command is available from within SAS Management Console or from the SAS Enterprise Guide Open Stored Process GUI as seen below (note you can only
"Help! My simulation is taking too long to run! How can I make it go faster?" I frequently talk with statistical programmers who claim that their "simulations are too slow" (by which they mean, "they take too long"). They suspect that their program is inefficient, but they aren't sure why.
It's been two years since my first trip to SAS UK for the SAS Professionals Convention. That was also my first trip to the UK, ever. I was pretty naive back then and didn't know what to expect from this strange land and its people. I was shown tremendous hospitality
I recently read a blog post in which a SAS user had to rename a bunch of variables named A1, A2,..., A10, such as are contained in the following data set: /* generate data with variables A1-A10 */ data A; array A[10] A1-A10 (1); do i = 1 to 10;
In the previous post on Broken Y-Axis, I reviewed different ways to display data as a Bar Chart, where the response values for some categories are many orders of magnitude larger than the other values. These tall bars force the display of other values to be squeezed down thus making it harder to compare
If you live anywhere in the Midwestern United States (you know who I'm talking about, those of you in the 12 states in the map to the right), you must be breathing a sigh of relief right about now. Why? Because the MWSUG (MidWest SAS Users Group) Call for Papers deadline
One of the coolest things that I saw at SAS Global Forum was Dr. Goodnight dissecting a hologram of a SAS high-performance server and describing how the technology works with analytics. This is the height of innovation. You have got to watch this! Here are a few great
Often we want to display data as a bar chart where a few observations have large values compared to the rest. Comparison between the smaller values becomes hard as the small bars are squeezed by the tall bars. Here is an example data, and a bar chart showing the data. The large values
In the summer of 2010, the LA Times made national waves by publishing Los Angeles Unified School District’s teacher names and value-added estimates. The New York Times followed suit in February, 2012, ranking New York City’s teachers based on their value-added ratings. While these bold actions may satisfy some parents
In the SAS/IML language, a user-defined function or subroutine is called a module. Modules are used to extend the capability of the SAS/IML language. In my blog posts, I usually define a module in a PROC IML session and then immediately use it. However, sometimes it is useful to store
I am part of a 'virtual team from SAS Technical Support' who provide the suggestions for the Tips & Techiques section for the SAS Tech Report each month. A couple of days ago, Bill Gibson, Chief Technology Officer from SAS Australia, sent us an email saying that like him, many
We're at stop #3 on the crash analytics highway. We've introduced the topic of the Four E's and have discussed the role of analytics in Enforcement. Now let's talk about Engineering. Safety, reliability and accessibility are all key components in road design. Traffic engineers work to make the driving environment
In the SAS/IML language, a user-defined function or subroutine is called a module. Modules are used to extend the capability of the SAS/IML language. Usually you need to explicitly load modules before you use them, but there are two cases where PROC IML loads a module automatically. Modules in IMLMLIB
Recently, I came across an interesting graph showing Euro contries bank exposuro to GIIPS countries, as percent of GNP. Here is the graph: I thought I would see how far I can get in making a similar graph using SAS. I made up some data with response values for a Product x
I found this great video on AllAnalytics.com. It was shot while you guys were at SAS Global Forum and has soooo many great SAS users talking about the reasons that you love to go to SAS Global Forum. Take a look: Now that you have heard their reasons, tell me
Put up or shut up is one of those great sayings from my generation. Loosely translated it means, stop complaining if you aren't going to do something about the problem. In this week's Innovation Inspiration, the author decided to teach American middle schoolers how to question the information that they
This post is a result of an intriguing question posed by a user on the SAS communities' page. How to create a bar chart where the category is a combination of two variables var_1 and var_2 (each with values of '+' and '-'), and get a X axis that shows each
