As a practitioner of visual analytics, I read the featured blog of ‘Visualizations: Comparing Tableau, SPSS, R, Excel, Matlab, JS, Python, SAS’ last year with great interest. In the post, the blogger Tim Matteson asked the readers to guess which software was used to create his 18 graphs. My buddy,

Thanks to Laurie Berzack, MSW, this week's guest blogger for the Work/Life Relationship Series! I've been a matchmaker for more than a decade, I've seen and heard it all. Do you really have no time to meet someone or is that merely an excuse? If you DO want to find the love of

Have you been using the SAS/Graph Gmap procedure to plot your data on maps for years, but never knew you could add roads to your maps?!? Follow along in this blog post, and I'll teach you how... But before we get started, here's a picture of a nice aerial view
Health care fraud prevention is a sticky topic. David Loshin discusses what's needed to balance prompt claims payments with fraud prevention efforts.
Some would say that it's impossible for blind users to see charts and graphs. Those same people might have once said it was impossible for the visually impaired to see the particles that comprise an atom, or galaxies that are billions of light years away. Innovation would prove them wrong
Ok, let’s just get this out of the way first. I love coffee! I mean, I LOOOVE coffee! The smell, the taste, the morning ritual, I love it all! Now, having said that, my goal for this blog is to be as unbiased as possible, and to provide the facts
Sometimes SAS programmers ask about how to analyze quantiles with SAS. Common questions include: How can I compute 95% confidence intervals for a median in SAS? How can I test whether the medians of two independent samples are significantly different? How can I repeat the previous analyses with other percentiles,
Editor's note: This series of blogs addresses the questions we are most frequently asked at SAS Press! In our last post about how to write a good outline, we discussed the importance of developing an outline for your proposed SAS Press book and gave some tips on how to do
What?!? You mean a period (.) isn't the only SAS numeric missing value? Well, there are 27 others: .A .B, to .Z and ._ (period underscore). Your first question might be: "Why would you need more than one missing value?" One situation where multiple missing values are useful involves survey data. Suppose
As you work toward data compliance, Dylan Jones says keep it simple – start with the 4F’s: Function, Flow, Form, Foster. Part 1 looks at the first two.
The SAS® Output Delivery System provides the ability to generate output in various destination formats (for example, HTML, PDF, and Excel). One of the more recent destinations, ODS Excel, became production in the third maintenance release for SAS 9.4 (TS1M3). This destination enables you to generate native Microsoft Excel formatted
Many introductory courses in probability and statistics encourage students to collect and analyze real data. A popular experiment in categorical data analysis is to give students a bag of M&M® candies and ask them to estimate the proportion of colors in the population from the sample data. In some classes,
While The BFD normally favors a lighter approach, with a focus on forecasting process (the politics and personalities therein), forecasting news, and forecasting gossip, we sometimes have to get serious. In this guest blogger post from Koen Knapen, Principal Consultant at SAS Belgium, Koen takes us into the netherworlds of
Thanks to Sara Thatcher, LCSW, for today's Relationship Series guest blog. So you are married with a toddler…Who has time for a spouse? Becoming a parent completely changes the dynamic between spouses. Sleeping in and cuddling with your beloved on weekends is replaced by little voices requesting your undivided attention
I’ve always loved watching crime series or films – from Homeland and True Detective to Sherlock Holmes. But after years of building software products and solutions designed to help security and law enforcement agencies solve crimes, I've noticed there are several clichés that need to be conquered by technology. No.
Are your friends passing around clever memes (supposedly) featuring something your favorite actor said, or sharing news articles that you think might be "fake news"? If there's even a hint of data analyst in you, then you probably check the actual data, and confirm or disprove the supposed facts yourself. I
The morning sunrises have been exceptionally beautiful this winter. Vibrant colors of fiery pinks and orange give way to bright blue skies and white fluffy clouds. There is something magical about being connected to nature, especially in the early morning before life has awoken. It takes me back to my
Corporate compliance with an increasing number of industry regulations intended to protect personally identifiable information (PII) has made data privacy a frequent and public discussion. An inherent challenge to data privacy is, as Tamara Dull explained, “data, in and of itself, has no country, respects no law, and travels freely across borders. In the
A categorical response variable can take on k different values. If you have a random sample from a multinomial response, the sample proportions estimate the proportion of each category in the population. This article describes how to construct simultaneous confidence intervals for the proportions as described in the 1997 paper
If “ugh” is the response that comes to mind when you remember today is Valentine’s Day – this is the post for you! We want you to have a GREAT night tonight. A great night doesn’t have to be filled with over-the-top activities. A great night can consist of doing something
When mentioning to friends that I’m going to Orlando for SAS Global Forum 2107, they asked if I would be taking my kids. Clearly my friends have not attended a SAS Global Forum before as there have been years where I never even left the hotel! My kids would NOT enjoy it… but,
In this post I wanted to shed some light on a visualization you may not be using enough: the Word Cloud. Word association exercises can often be a fun way to pass the time with friends, or it can trigger immediate action – just think of your email inbox and

After the recent presidential election, I was updating my graphs of the voter registration data and noticed that the number of registered voters decreased after the election. At first I thought that was odd, but then I realized that maybe inactive voters were being purged. I wanted to find out
The term compliance is most often associated with control. It evokes visions of restrictions, regulations and security protecting something which is to remain private. The term open is most often associated with access, and it evokes visions of an absence of restrictions, regulations and security – making something available which is
A common question on SAS discussion forums is how to repeat an analysis multiple times. Most programmers know that the most efficient way to analyze one model across many subsets of the data (perhaps each country or each state) is to sort the data and use a BY statement to
Are you struggling to hire talented data scientists to glean insights from your corporate data? There’s currently a lack of big data talent hampering corporate analytics and causing nightmares for CIO’s, but I have good news for you: You may already have all the data scientists you need! There are
