Streaming analytics is a red hot topic in many industries. As the Internet of Things continues to grow, the ability to process and analyze data from new sources like sensors, mobile phones, and web clickstreams will set you apart from your competition. Event stream processing is a popular way to
In my SAS Press book Business Statistics Made Easy in SAS® I place a strong focus on the skill of extrapolating analytics/statistical outcomes to key business implications (similar techniques can be used to link statistics to other key societal outcomes). Unfortunately, business analytics often stops short of defining the impact
Math lovers, do you know what day it is? It's Pi Day, which we celebrate every year on March 14 because the date 3-14 matches the first three digits of pi, 3.14. This year, I'm celebrating with poetry, combining my love of math with my love of language. Word Spy explains that a pi-ku is
People have always been fascinated by sports statistics, and with the recent popularity of fantasy sports there is an increased demand for custom analyses of the sports data. With those folks in mind, I have created a simple example that SAS programmers can use as a starting point for analyzing NBA
In the past, we've always protected our data to create an integrated environment for reporting and analytics. And we tried to protect people from themselves when using and accessing data, which sometimes could have been considered a bottleneck in the process. We instituted guidelines and procedures around: Certification of the data
Today is March 14th, which is annually celebrated as Pi Day. Today's date, written as 3/14/16, represents the best five-digit approximation of pi. On Pi Day, many people blog about how to approximate pi. This article uses a Monte Carlo simulation to estimate pi, in spite of the fact that
I was answering questions about SAS in a forum the other day, and it struck me how much easier it is to help folks if they can provide a snippet of data to go along with their program when asking others to help troubleshoot. This makes it easy to run
Administration einer SAS Umgebung: Wir holen das Beste aus Ihrer SAS Umgebung heraus – das ist unser Motto. Sie stehen vor einem umfangreichen SAS Metadaten Security Review? Einer SAS Migration oder einem Umzug auf eine neue Infrastruktur? Sie schieben die längst notwendigen Aktivitäten immer wieder vor sich her, weil Sie
How many of us have used the phrases… It’s a piece of cake Anyone can do it It’s as easy as ABC I could do it with my eyes shut When it comes to business intelligence it should be “easy peasy” but for many organization it can still be a
The importance of data analytics in the UK public sector and wider society was in the spotlight earlier this year, following a report from Policy Exchange. It called for elected mayors to set up an Office of Data Analytics. If enacted, these teams of experts will have one central aim:
When you spend long enough writing and working in any industry, you inevitably see trends emerge and reach varying levels of maturity. Data governance is one such trend, as you can see from the following Google Trends chart:
Do you like a good horror story? Then may I suggest “Future Crimes” by Marc Goodman. When it comes to this genre, Wes Craven, John Carpenter and Stephen King have got nothing on Goodman, primarily because Goodman’s story is non-fiction. Scene 1: The present – Your workstation or data center Whether
You can use histograms to visualize the distribution of data. A comparative histogram enables you to compare two or more distributions, which usually represent subpopulations in the data. Common subpopulations include males versus females or a control group versus an experimental group. There are two common ways to construct a
Our colleagues at the SAS office in Korea recently had the opportunity to interview two customers from KT, one of the biggest telecommunications companies in Korea, about getting SAS certified. Sung-chul Hwang and Gyu-seob Lee both have four SAS certifications – Base Programmer, Advanced Programmer, Statistical Business Analyst and Predictive
We recently had a flooding event at Jordan Lake where the water rose almost 20 feet above normal. This blog details that flooding event in both photos and graphs. If you're intrigued by weather, boats, or lakes then this blog's for you! In NC's Research Triangle Park area, there are basically two

Händler und Handel haben heutzutage Zugang zu einer enormen Menge an Daten – und damit die Grundlage für eine personalisierte Ansprache, die Kunden inzwischen erwarten. Richtig eingesetzt, kann Analytics der Schlüssel für alle möglichen Geschäftsvorteile sein – sei es, dass es darum geht, ein besseres Online-Erlebnis für den Kunden zu
Most SAS regression procedures support the "stars and bars" operators, which enable you to create models that include main effects and all higher-order interaction effects. You can also easily create models that include all n-way interactions up to a specified value of n. However, it can be a challenge to
In previous articles, I've shared tips about how you can work with SAS and ZIP files without requiring an external tool like WinZip, gzip, or 7-Zip. I've covered: How to create ZIP files with ODS PACKAGE ZIP (available since SAS 9.2) How to "unzip" and read ZIP files using FILENAME
On a recent CBS Sunday Morning episode Dr. Phil McGraw of “Dr. Phil” fame was featured. During the segment he talked about shifting his focus from golf to tennis. To paraphrase, he said golf drove him crazy because he couldn’t bear down, run faster, sweat harder and be better. I
In my previous blog post I talked about how the rapid and varied growth of data calls for states to consider an enterprise analytics program, in the form of a Center of Analytics. This entry, first posted as an article on Government Executive's Route Fifty, gives the most important success
This is my second article about voice of customer analysis; you can find the first here. The first time we discussed that a simple sentiment polarity score was a rather a narrow view. This time we will examine a more insightful approach, using voice of customer analysis to monitor customers’ opinions
In der Vergangenheit hat sich die Agilität von BI-, Big Data- und Analytics- Anwendungen (Datenarchitekturen) als Erfolgsfaktor für Unternehmen aus unterschiedlichsten Branchen erwiesen. Gerade die Integration neuer Datenquellen in bestehende DWH-Architekturen und die daraus resultierenden Anpassungen resultieren in langwierigen Entwicklungsprozessen.
I took my first Uber ride recently. I was with a colleague and we were going into the office before dawn to finish a presentation we were making later that morning. As our Uber driver accelerated to merge onto the interstate, we heard a high-pitched whine and smelled hot metal
I've been doing some investigation into Apache Spark, and I'm particularly intrigued by the concept of the resilient distributed dataset, or RDD. According to the Apache Spark website, an RDD is “a fault-tolerant collection of elements that can be operated on in parallel.” Two aspects of the RDD are particularly
There’s been quite a lot of chatter lately about my Boston Red Sox and their recent shift ‘away’ from using analytics or ‘sabermetrics,’ as data science is often referred to in baseball (Jeff Passan, one of my favorite baseball writers, chimes in here – Forbes also commented that the Sox are
Have you ever found a graph of some interesting information, but the graph was difficult to understand (or even misleading). I strive to fix those graphs - this time it's a graph of US immigration data... I found the following immigration graph on the flowingdata website - it's a screen-capture of
Last week I showed how to create dummy variables in SAS by using the GLMMOD procedure. The procedure enables you to create design matrices that encode continuous variables, categorical variables, and their interactions. You can use dummy variables to replace categorical variables in procedures that do not support a CLASS
When I am discussing my new Explaining Analytics course with analytic professionals, I frequently hear, “I have a co-worker that needs the class.” That comment is much more frequent than – “Hey I need that class.” The truth of the matter is we all need to continue to improve –
April 7, 2003 will go down in the history books for me. The streets of Syracuse, New York, were abuzz. I was a junior television major, and our men’s basketball team had just won its first NCAA basketball title. Our three-seed Orangemen had bested #2 Kansas in New Orleans, but the
