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
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
In meinem Blogbeitrag zum Reisemarkt habe ich rhetorisch gefragt, wann Sie das letzte Mal in einer Filiale des Reiseanbieters waren. Nun stelle ich die gleiche Frage: Wann haben Sie das letzte Mal ihre Bank besucht …?
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
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
