Editor's note (4/11/17): Full proceedings from SAS Global Forum 2017 (including for the presentations mentioned in this blog) can be found at http://support.sas.com/resources/papers/proceedings17/. SAS Global Forum 2017 is just a month away and, if you’re a SAS administrator, it’s a great place to meet your peers, share your experiences and attend
It is no secret at all that there is a world of difference between theoretical and applied econometrics. Every analyst, as a practising econometrician, experiences this moment in their processional career – usually at the beginning of it – when the theory acquired during their academic time clashes with the practice. They
In 2011, Loughran and McDonald applied a general sentiment word list to accounting and finance topics, and this led to a high rate of misclassification. They found that about three-fourths of the negative words in the Harvard IV TagNeg dictionary of negative words are typically not negative in a financial
.@philsimon raises some chilling questions about the IoT and current threats.
Monte Carlo techniques have many applications, but a primary application is to approximate the probability that some event occurs. The idea is to simulate data from the population and count the proportion of times that the event occurs in the simulated data. For continuous univariate distributions, the probability of an
DevOps is enjoying a lot of attention at the moment, mostly because of its promise to increase software quality at lower cost. DevOps is a hybrid term linking development and operations. It's a philosophy that focuses on improving efficiencies in how we build and deliver software, solutions and the supporting environments.
As a single mom of 10 years, I have vacillated back and forth from “There is no evening that I wouldn’t rather take a bath than go on a date” to “ok, this might be fun.” Mostly, thinking about dating as a single parent just makes me tired. Whether you
At its core, data compliance is built on simple foundations. Dylan Jones closes this series by explaining the remaining components of the "4F framework."
Does your data just look like a bunch of dots? Would you like to bring those dots to life so they can tell their story? This example shows how to make some voter-registration dots a bit more lifelike, so you can see what they're saying. You can apply the same
Do you remember the 90s? It seemed like every company and organization had some sort of strategic plan that had “2000” in its title. And they were all going to achieve and exceed these Year 2000 goals … if their systems didn’t crash at 12:00:01 on January 1, 2000! So
What to watch out for when chief data officers begin to appear in our country Recently and for the first time, I met someone whose business card title read ‘Chief Data Officer’ at one of our customer’s places of business. It wasn’t in Slovakia, but I am convinced that it
To show how they're compliant with regulatory mandates, organizations first need an enterprise data strategy. Joyce Norris-Montanari discusses the issues.
Longtime SAS programmers know that the SAS DATA step and SAS procedures are very tolerant of typographical errors. You can misspell most keywords and SAS will "guess" what you mean. For example, if you mistype "PROC" as "PRC," SAS will run the program but write a warning to the log:
Manufacturers are used to operating in challenging circumstances – whether financial, economic, political or competitive. And it's a good thing since the coming years seem likely to be as uncertain as those following the global economic crash. But manufacturing will have an excellent opportunity to thrive because, like many sectors,
Let’s have some fun, shall we? Share your video or photo! The SAS User Community, albeit spread around the world, is a tight-knit group. We may sit alone in our offices pounding out code, developing applications, tweaking system performance or creating reports, but the truth is other SAS users (our
Erwin Kalvelagen recently posted about a logic puzzle called Kakuro, also known as Cross Sums. As in traditional crossword puzzles, there are horizontal and vertical clues. As in Sudoku, each white cell is to be filled in with a digit from 1 to 9, with no digit repeated within the
Editor's note: This series of blogs addresses the questions we are most frequently asked at SAS Press! It worth spending some time on this. Arguably, this is one of the most important parts of the book. The table of contents and outline provide the blue print of your book –
Machine learning is a type of artificial intelligence that uses algorithms to iteratively learn from data and finds hidden insights in data without being explicitly programmed where to look or how to find the answer. Here at SAS, we hear questions every day about machine learning: what it is, how it compares to
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,
.@philsimon advises to be wary of those promising obvious and facile solutions to increasingly challenging governance and privacy issues.
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
Editor's note: Amanda Farnsworth is Head of Visual Journalism at BBC News and a featured speaker at SAS Global Forum 2017, April 2-5, 2017 in Orlando. There was a best selling book some years ago called “Men are from Mars and Women are from Venus.” It’s a phrase I thought
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
