In 2013, Rick Wicklin blogged about visualizing matrices as heat maps using SAS/IML. That post reminded me that we had done a similar thing for the coefficient matrices in our optimization problems. In particular, we have developed some SAS macros to visualize the input data sets for the OPTLP (linear
Bubble Plots provide additional ways to visualize your data. The plot supports display of multiple response characteristics of the data in one graph. Bubble plots were introduced with SAS 9.3 in GTL and SG Procedures. A bubble is drawn at each (x, y) point in the graph, and each bubble is
La ciencia de datos es un tema álgido entre los líderes empresariales y de TI. Hay un entusiasmo evidente por los beneficios potenciales que tienen las organizaciones cuando la adoptan en sus procesos, sin embargo, el hallazgo, contratación y entrenamiento de científicos de datos para conformar el equipo, también genera
In just one weekend Shang-Hua Wu went from a SAS user to a super SAS user by getting not just one, but two SAS certifications – SAS Certified Base Programmer and SAS Certified Advanced Programmer. Wu wanted to earn his certifications to position himself for new career opportunities in the
Updated Oct 2023 You may have heard that the World Health Organization (WHO) released its new Sugar Guidelines which recommend keeping Added Sugar to less than 5% of our total calories or 6 teaspoons of Added Sugar per day. To give you an idea of what 5% of your total
If you use a GPS system or a mapping app on your phone, you're familiar with geospatial intelligence. But did you know this same technology can be used to map the spread of diseases, to understand the spread of wildfires, to visualize environmental issues - and much more? The proliferation
Big data. Streaming data. Complex data. We’ve all heard the reasons why organizations feel like they’re facing an insurmountable data challenge. Now, it’s time to do something about it. For the past few years, SAS has helped some of the world’s leading companies make sense of an avalanche of data.
Discovery Channel's Shark Week starts July 5, 2015 - and I've created a special SAS map & graph of shark attacks in North Carolina to get you in the mood for their week of shark education! But first, to get you in the mood for my blog, here's a picture

Hello, I’m Jennifer Waller, your SAS Global Forum 2016 conference chair. This is the first of several blogs I’ll be writing to help keep you informed about the conference and ways you can get involved. Because of my background in education, I’m especially excited about a new initiative at this
Textmining ist im Grunde wie Recycling, eine Art Alchemie, die aus unstrukturierten strukturierte Textdaten macht. Ich kann einiges Unbrauchbare vorne rein kippen und hinten kommt Brauchbares und Neues raus. Je besser das Rohmaterial allerdings ist, desto besser das Ergebnis. Dann veredelt unser Recyclingautomat den unstrukturierten Input. Und darüber möchte ich
One of my earlier blogs on handling percent (%) values in SAS was very popular (it's been viewed over 34,000 times!), so I thought I'd write a similar blog on handling time (mm:ss.ss) values in SAS ... This past weekend I was in a dragonboat race (that's me in the
Love them or hate them, value-added models (VAMs) have changed the way we look at education today. VAMs have reshaped our thinking about the effectiveness of programs, schools, educators and colleges that prepare them. While VAMs have been used in the social sciences for decades, we can credit a few
Haben Sie schon einmal ein Business Intelligence (BI) oder Analytics Projekt von Anfang an begleitet? Dann wissen Sie sicher wie aufwendig die erste Phase (Datenzugriff und Datenaufbereitung) sein kann. Marktanalysten schätzen das Verhältnis Vorbereitung der Daten zur eigentlichen Auswertung auf 80:20. Das heißt, im Normalfall wird der weitaus größte Teil der
Within the SAS DATA step, the LAG function is provided to return a variable’s value from a previous data set observation. With certain data criteria, sometimes there is a need to look ahead at the next observation and you would expect to use a LEAD function, but this does not
