Many people today just use their computer to play Angry Birds or post pictures of their most recent meal on Facebook ... but what would some of the great minds of the past have done with a computer?... For example, Charles Minard was creating impressive information graphics without a computer over 100 years ago,
SAS conferences are amazing events, with great presentations, keynote talks, classes and workshop, experts from the SAS Institute, networking opportunities and so much more! With so many things to do and so much happening at once, SAS conferences can be overwhelming. Plan to get the most out of your conference
If you've ever tried to use PROC FREQ to create a frequency table of two character variables, you know that by default the categories for each variable are displayed in alphabetical order. A different order is sometimes more useful. For example, consider the following two-way table for the smoking status
I am happy to report that my new book "Getting Started with the Graph Template Language in SAS" is now shipping. A colleague suggest it would be useful to post some articles with the same theme of "Getting started". I thought that was a great idea, and decided to start a new
Stick to the basics. Did you ever get that advice? Two of the papers at MidWest SAS Users Group 2013 used that most fundamental of SAS processing concepts—the Program Data Vector—to show why users might encounter unexpected errors in their DATA step programs. In The Secret Life of DATA STEP,
In SAS Grid Manager environments, SAS administrators must often set up separate configurations based on a mix of requirements for departments, client applications and user roles. To accomplish this in previous SAS releases, administrators must define multiple SAS Application Server contexts, each with its own grid server definition and associated options.
This graph certainly makes it clear! I can see right through your lies! Clearly, you know what you're talking about! We need more transparency in our organization! What was that all about, you might ask?!? ... I was just getting all the obvious puns out of the way, so I
Ginger is one of those spices that is good in anything! Sweet or savory. Ginger has a sweet, pungent spicy kick to it. You can find ginger fresh in the produce section of most stores, or as the dried ground spice. But, if you’ve never cooked with fresh ginger, you
A challenge for statistical programmers is getting data into the right form for analysis. For graphing or analyzing data, sometimes the "wide format" (each subject is represented by one row and many variables) is required, but other times the "long format" (observations for each subject span multiple rows) is more
I'm currently at the SESUG conference with hundreds of SAS users. I've presented a few talks, and I've attended a few more. The presentation rooms can be large and dimly lit, and the projectors at these conference hotels are not always the brightest nor are they exactly "high def". To
SAS/IML programmers know that the VECDIAG matrix can be used to extract the diagonal elements of a matrix. For example, the following statements extract the diagonal of a 3 x 3 matrix: proc iml; m = {1 2 3, 4 5 6, 7 8 9}; v = vecdiag(m); /* v = {1,5,9}
Last week Bruno asked about creating a Schedule Chart using SG Procedures. To me, such projects are very interesting and challenging...How much mileage can we get out of the current set of SGPLOT procedure features to create a visual that was not part of the original requirements? The clear choice for
The other day I showed how to check your data cardinality by using a simple SAS program. I also promised to provide a custom task that makes the process even easier within SAS Enterprise Guide. Today I'm delivering on that promise. I've just added the custom task to the support.sas.com
We are in the final countdown to the Analytics 2013 Conference to be held next week, October 21-22 at the Hyatt Regency Orlando. There is a power-packed agenda for the conference, featuring four very strong keynote presentations from Dr. Jim Goodnight, CEO of SAS; Ed Gaffin, Walt Disney World; Will Hakes,
This article is about rotating matrices. No, I don't mean "rotation matrices," I mean rotating matrices. As in turning a matrix 90 degrees in a clockwise or counterclockwise direction. I was reading a program written in MATLAB in which the programmer used a MATLAB function called ROT90, which rotates a
Although the NSA and news media have given metadata a bad name in the popular press, the fact remains that information about the nature of your data is extremely valuable. For example, I posted an article yesterday about data cardinality. Cardinality measures the uniqueness of values in a variable. Cardinality
As you've probably guessed, I'm a "visual" person - I like to see things (in a chart/graph/map) rather than just reading about them (in a data table and summary statistic). Don't get me wrong - I'm a big fan of statistics and analytics -- but I'm an even bigger fan of
If you have been reading the articles in this blog, you already know that the Graph Template Language (GTL) forms the underlying foundation for all graphs produced automatically from SAS analytical procedures and custom graphs created with the SG Procedures and the ODS Graphics Designer. SG procedures and Designer provide
"Do I really need a detailed technical architecture before I start my SAS Deployment?" My team gets asked these questions all the time: Do we really need to spend the time for the above exercise? Why can’t we just start doing the deployment of SAS and fix issues if they come
Data cardinality is an important topic for for data analysis. In mathematical terms, cardinality is simply the number of elements in a set. But in data applications, cardinality signifies the number of unique values for a given field of data. Related terms include number of levels (thank you, PROC FREQ
On Kaiser Fung's Junk Charts blog, he showed a bar chart that was "published by Teach for America, touting its diversity." Kaiser objected to the chart because the bar lengths did not accurately depict the proportions of the Teach for America corps members. The chart bothers me for another reason:
The Inside SAS Global Forum video series has been officially launched for 2014. Yes, the conference is still several months away, but it is not too soon to plan! Your first item of business: submit your proposal for content. Then next: register for the conference. Anna Brown and I provide
Don't ask me how it happened, but in my quest for even more SAS fame, I managed to muscle my way onto the set for Inside SAS Global Forum, the video series that focuses on everything that you need to know about SAS Global Forum 2014. After a brief cooling
Yesterday I read a Christina's blog article on the winners of the Best Presentations honor at MWSUG 2013. Two papers caught my (graphical) eye, both by Perry Watts. Perry has done a marvelous job describing how creatively use GTL to make graphs that may not be obvious at first glance.
If you know what this means, you’ll love our news! SAS Global Forum 2013 was the official “Year of the Poster”, and conference chair Rick Mitchell and his team more than tripled the number of poster submissions. Posters are indispensable for visual content. Poster presentations are also a huge asset
Should you ever guess on the SAT® or PSAT standardized tests? My son is getting ready to take the preliminary SAT (PSAT), which is a practice test for the SAT. A teacher gave his class this advice regarding guessing: For a multiple-choice questions, if you can eliminate one or two
My aunt Susanne is an elderly lady, who lives at the countryside and looks forward to celebrating her 80th birthday soon. Since the 1960's she has had a telephone connection with her fixed line provider. At that time, and for many years later, in the country where my aunt lives,
Congratulations to Best Paper Winners from MidWest SAS Users Group conference! You'll want to read these, and check the MWSUG 2013 proceedings for other useful papers from the recent conference. Start planning now for MWSUG 2014 in Chicago.
In my last blog post I described how to implement a "runs test" in the SAS/IML language. The runs test determines whether a sequence of two values (for example, heads and tails) is likely to have been generated by random chance. This article describes two applications of the runs test.
Recently I delivered a SAS Talks session: SAS 9.4: What’s New for SAS® Administrators . We had a large group attend and subsequently had a wonderful flood of questions that we couldn’t always keep up with. So I wanted to follow up with some of the popular questions:
