Many of you know Mike Zdeb. He's a long-time SAS user and frequent presenter at SAS conferences. Zdeb is also a reviewer of many SAS Press books and author of his own SAS book, Maps Made Easy Using SAS. Zdeb contacted me after he read the May SAS Tech Report
The Swiss army knife is known for its versatility, with a variety of tools and blades to help you complete the task at hand. When you are creating graphics, you sometimes have a special feature you want to add, but you can't seem to find the right syntax "tool" to
Unlike many of you, data hasn’t always ruled my world. Though I took statistics and economics classes in college, I built my academic career around studying history and writing papers like “The Importance of the Family Dinner in Preserving the Italian Culture among Immigrants.” Don’t laugh; it earned me an
No matter what statistical programming language you use, be careful of testing for an exact value of a floating-point number. This is known in the world of numerical analysis as "10.0 times 0.1 is hardly ever 1.0" (Kernighan and Plauger, 1974, The Elements of Programming Style). There are many examples
According to Janet Stuelpner and Joseph Hantsch, the authors of the 2012 SAS Global Forum paper, One at a Time; Producing Patient Profiles and Narratives, patient profiles are used several ways depending upon the 'customer' need.
A reader wrote for help with a computational problem. He has a vector of length N and the vector contains integer values in the range [1, 120], which represent months for which events occurred over a 10-year period. The question is: what is the 24-month period for which the most
This is a third post on newspaper stories that I recently read. Today's post deals with science, politics, and rising sea levels. Incidentally, the title is a blatant reference to John Allen Paulos's brilliant book, A Mathematician Reads the Newspaper. Senate approves law that challenges sea-level science The NC legislature
Can you actually get something for nothing? With PROC SQL’s subquery and remerging features, yes, you can. Often there is a need to add group descriptive statistics such as group counts, minimum and maximum values for further by-group processing. Instead of first creating the group count, minimum or maximum values
This is my second post on some newspaper articles that I recently read. Today's post deals with academic fraud. Questions linger in academic fraud case Over the past year, the News and Observer has occasionally reported on a scandal at the University of North Carolina at Chapel Hill in which
This past weekend was Father's Day, so I took some time to relax and read the newspaper. I found several stories that suggested interesting statistical questions. Unfortunately, the data are not available for analysis. Nevertheless, the stories are worth sharing. Over the next few days, I'll post my thoughts on
Wizard Harry Potter makes magic just waving his wand around and shouting out spells. Using SAS Enterprise Guide (and you are welcome to shout out your own commands too) you can create some magic, allowing the Stored Process Wizard to code for you. On Step 2, the "Include code for"
To celebrate special occasions like Father's Day, I like to relax with a cup of coffee and read the newspaper. When I looked at the weather page, I was astonished by the seeming uniformity of temperatures across the contiguous US. The weather map in my newspaper was almost entirely yellow
Statistical graphs often include display of derived statistics along with the raw data. Often these statistics are presented in a tabular format inside the graph. With SGPLOT procedure, a table of statistics can be added to the graph as an inset table, as shown below. Using a Stat Table: SGPLOT code:
The first time that I saw a demonstration of SAS Visual Analytics Explorer was awesome, but it didn't give me goosebumps. I got goosebumps the size of golfballs during SAS Global Forum Opening Session when Dr. Goodnight sat down at a computer screen and began to demonstrate how effortlessly users can
ODS Graphics components like GTL and SG procedures are designed to work with Styles to create graphs that are effective in the delivery of information and aesthetically pleasing out of the box. You no longer have to tweak the colors to ensure a nice graph. The graph derives all the
A colleague was recently working with a web service that supplies some datetime values using the Microsoft Windows internal representation. He called the web service to retrieve those values (along with other data) from SAS, and he needed convert these values to SAS date-time values. The Microsoft definition for a
When I was growing up, summertime always meant a road trip to see my grandparents and great-grandparents in Concord, California, just outside San Francisco. Most of our time in Concord was spent shuffling between relatives but my parents always made time for a day trip into San Francisco. On these
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.
