Was gibt es zu „Big Data“, das nicht schon „big-time-häufig“ gesagt, geschrieben, irgendwo kopiert und wieder niedergeschrieben wurde? Und damit Big Data erst möglich macht? Eine ganze Menge! Professor Viktor Mayer-Schönberger eröffnete den zweiten Tag der re:publica auf der großen Bühne mit diesem Thema. Nachfolgend fasse ich den Vortrag zusammen – mit

This SAS tutorial video will show you how to generate plots for two continuous numeric variables with Base SAS. Basic scatter plots, linear or curvilinear regression lines, confidence intervals or ellipses, and multiple plot overlays are demonstrated. To learn more about this topic, check out our SAS Programming 1: Essentials
It was just a couple of years ago that folks were skeptical about the term "data scientist". It seemed like a simple re-branding of an established job role that carried titles such as "business analyst", "data manager", or "reporting specialist". But today, it seems that the definition of the "Data
In my recent post on how to understand character vectors in SAS/IML, I left out an important topic: How can you allocate a character vector of a specified length? In this article, "length" means the maximum number of characters in an element, not the number of elements in a vector.
Según datos de la Asociación Mexicana de Internet A.C. (AMIPCI), la mitad de los usuarios de Internet en México se conectan a la red a través de dispositivos móviles y se espera que para el 2015, las aplicaciones móviles (Apps) superen a las de escritorio no sólo en el país
In my previous post in the Ask the Statistician interview series, we heard from statisticians at the Analytics 2013 conference discuss the how their statistical results are put into action within their organizations. Now let’s learn more about their specific examples of success they have had utilizing these results. Check out
I'm currently working on a large project for a SAS customer. The project comprises many activities and phases, so there is a need to track progress on many different levels. During a recent meeting the project manager announced, "I'm putting together a status deck, and I'll include some Harvey Balls
El Big Data y la Nube se están volviendo inseparables: “se necesitan recursos en la nube para el almacenamiento y la ejecución de proyectos de big data, y el big data brinda a las compañías una buena ocasión de pasar a la nube”. Podríamos decir que el big data y
In my previous post, I discussed sampling error (i.e., when a randomly chosen sample doesn’t reflect the underlying population, aka margin of error) and sampling bias (i.e., when the sample isn’t randomly chosen at all), both of which big data advocates often claim can, and should, be overcome by using all the data. In this
Last week Chris Hemedinger posted an article about spam that is sent to SAS blogs and discussed how anti-spam software helps to block spam. No algorithm can be 100% accurate at distinguishing spam from valid comments because of the inherent trade-off between specificity and sensitivity in any statistical test. Therefore,
Jill Dyché, internationally recognized speaker, author and business consultant, spends her days talking to businesses about big data – how they’re using it, challenges, successes, strategies, plans and more. What she’s hearing again and again from IT leaders is that they have to innovate with big data, move quickly and
All my friends seem to be having twins these days (below is a picture of my friend Holly's twins, for example) - I wondered if I could use SAS to analyze this twinning trend ... When I was growing up, way back in the day, twins seemed to be rarity.
All Analytics spoke with several leaders at the recent SAS Global Forum Executive Conference on what it means to build an analytics culture. Here’s a video of those conversations. The video features several sections related to building an analytics culture: Kim Nevala, Director of Business Strategy for the SAS Best
Principle 5: Timeliness – A bank should be able to generate aggregate and up-to-date risk data in a timely manner while also meeting the principles relating to accuracy and integrity, completeness and adaptability. A timely and accurate view of risk exposure, aggregated across credit counterparties and financial products could have
SAS programmers are probably familiar with how SAS stores a character variable in a data set, but how is a character vector stored in the SAS/IML language? Recall that a character variable is stored by using a fixed-width storage structure. In the SAS DATA step, the maximum number of characters
Ofrecer a los mexicanos Educación de Calidad es parte de la Estrategia Digital Nacional; para llevar a cabo este objetivo el Gobierno de la República Mexicana plantea la integración y aprovechamiento de las TIC en el proceso educativo, de tal manera que sea posible insertar al país en la Sociedad
I'm an avid Star Wars fan, and am cautiously optimistic about what J.J. Abrams intends to do in Star Wars VII. The cast for the movie was revealed earlier this week, and today is May the Fourth, an unofficial Star Wars holiday. You might be asking yourself what any of
If you've followed technology news in the last few weeks, you've probably seen a proliferation of awestruck faces wearing blacked out goggles, similar to the image I'm using here. The goggles are Oculus Rift immersive VR headsets, and the news is the $2 billion dollar acquisition of Oculus by Facebook.
My oldest son is in the school band, and they are getting ready for their spring concert. Their fall concert was wonderful; hearing dozens of students with their specific instruments playing together creates beautiful, rich sounding music. The depth of sound from orchestral or symphonic music is unmatched. In data
Ed wants to make sure that the next generation of technology is accessible, and the best way to do that is to ensure the next generation of computer scientists understand the needs of users with disabilities. So, he and I get out of the office on a regular basis to
As we saw in Steve Morlidge's study of forecast quality in the supply chain (Part 1, Part 2), 52% of the forecasts in his sample were worse than a naive (random walk) forecast. This meant that over half the time, these companies would have been better off doing nothing and
Debido al crecimiento masivo de las Tecnologías de la Información en la última década, el Chief Information Officer (CIO) ha pasado de tener una función de apoyo de back-office a una unidad de negocio crítica para las decisiones rentables del negocio. En la actualidad se ubica entre las cinco áreas con
In his recent Financial Times article, Tim Harford explained the big data that interests many companies is what we might call found data – the digital exhaust from our web searches, our status updates on social networks, our credit card purchases and our mobile devices pinging the nearest cellular or WiFi network.
While at a conference recently, I was asked whether it was possible to use SAS to simulate data from an inverse gamma distribution. The SAS customer had looked at the documentation for the RAND function and did not see "inverse gamma" listed among the possible choices. The answer is "yes."
Viktor Mayer-Schönberger ist Oxford-Professor, Berater internationaler Organisationen sowie einer der Keynote-Speaker der re:publica 2014. In seinem Bestseller „Big Data: Eine Revolution, die unser Leben verändern wird" wirft er ein kritisches Licht auf Big Data Analytics – zeichnet aber auch positive Szenarien auf. Wir haben ihn gefragt zu seinen Forderungen an
With tornadoes in the news lately, I wondered how I might could use SAS to analyze tornado data. How about animating 60 years of tornado path data? ... I was using Google to search for ways to analyze tornado data, and found an example on ustornadoes.com that animates the tornado
I led an analytical culture track at the SAS Global Forum Executive Conference last month in Washington, DC. I talked with leaders in fields as diverse as healthcare, chemical manufacturing and government. Although these organizations have very different operating models, their challenges, comments and questions were similar. They all recognized
I was asked to speak recently on a topic that includes two hyped terms: Big data and sustainability. At the risk of igniting an anti-buzzword campaign, I added a third over-used term to that list: analytics. Even though individuals and companies use those three words – big data, sustainability, and
With as much as I travel, I have to confess that I’ve become a bit of a food snob. And for good reason, I might add. Two days in a Chilean hospital will make anyone stick with what they know and trust. After that experience, it was just me and
