Young digital natives are learning chess at an unprecedented rate. Three-year-olds learn chess from the tablet and quickly become more knowledgeable than their parents. But unlike most tablet games, chess is a gateway to Science, Technology, Engineering and Mathematics (STEM) education. We grown-ups must optimize the chess-to-STEM pipeline, but how? Consider this
Order must be the most frequent cry for help in the SAS classroom. “HELP,” said my student in the classroom. “I work with messy health data. My users want to see data in this order.” T1.col1, t1.col2, t1.col3, t1.col4, t2.col5, t1.col6 and list the remaining columns in column position from
In my previous blog post, I showed how to use log axes on a scatter plot in SAS to better visualize data that range over several orders of magnitude. Because the data contained counts (some of which were zero), I used a custom transformation x → log10(x+1) to visualize the
Data visualization tools are a great way to create impactful reports. A well designed report can give users an understanding of their data quickly and easily. And with tools like SAS® Visual Analytics, users can now quickly visualize and understand vast amounts of data. However, with all the visualization options
SAS users love to look at data. And the data grid in SAS Enterprise Guide is a convenient way to view the contents of a data set. While small data sets can be rendered lickity-split for quick viewing, sometimes people get justifiably anxious when opening very large data. Perhaps they've
Recently, the American Statistical Association (ASA) released a statement about value-added modeling. This statement was widely covered in the national press, some of which positioned the statement as a significant blow to value-added modeling. However, the ASA statement did not “slam” value-added modeling; rather, the statement’s authors advocated statistical rigor,
Business Intelligence (BI) can mean many things to many people, but generally BI is associated with business reports. When you fold business analytics (BA), especially advanced analytics that are predictive or prescriptive, under the BI umbrella you inherently dilute the value proposition that analytics can provide to an organization. Why
I bet a lot of SAS users know where the phrase "Live Long and Prosper" comes from ... but can we use SAS software to also help analyze 'how long'? This blog posting shows several different kinds of SAS graphs that can help answer such a question! Let's start with
I have previously blogged about how the dark side of our mood skews the sentiment analysis of customer feedback negatively since we usually only provide feedback when we have a negative experience with a product or service. Reading only negative reviews from its customers could make a company sad, but could reading only
Visual analytics es una solución, que puede impactar los resultados de una compañía independientemente del tamaño. Según Sanjeev Aggarwal, socio de la consultora tecnológica SMB Group, Visual analytics es el futuro del análisis avanzado de datos para las empresas en crecimiento. Las hojas de cálculo y las herramientas de Business
If you are trying to visualize numerical data that range over several magnitudes, conventional wisdom says that a log transformation of the data can often result in a better visualization. This article shows several ways to create a scatter plot with logarithmic axes in SAS and discusses some of the
The word “analytics” is widely misused and misunderstood. While SAS arguably invented the advanced analytics and predictive analytics categories more than 38 years ago, other software vendors have used the term to describe things like reporting, monitoring, and tracking what happened. The value of these more simple capabilities are easily
The SAS author’s tip of the week blogs are back! Sorry for the short break - I’ve been working to transition into my new role as editor of the SAS Bookshelf. We will continue to feature these helpful tips for our readers. Please let me know if there is any
A few years ago I blogged about how to expand a data set by using a frequency variable. The DATA step in the article was simple, but the SAS/IML function was somewhat complicated and used a DO loop to expand the data. (Although a reader later showed how to avoid
La influencia de las redes sociales aunada al incremento de dispositivos móviles y a la necesidad de adquirir productos personalizados transforma el mercado de telcos. Los consumidores son más exigentes y antes de adquirir un producto consultan otras alternativas, generalmente en internet. La decisión de ingresar o permanecer en una
Facebook spielt mit den Gefühlen: Fast 700.000 Nutzer nahmen 2012 an einer psychologischen Studie teil. Unfreiwillig und unwissentlich. In diesem Facebook-Experiment wurde der Hälfte der Nutzer ein manipulierter Nachrichten-Feed angezeigt. Geprüft werden sollte, ob Themen und Tonalität der Fake-News die Stimmung der User beeinflusst. Die Studie wurde Anfang Juni veröffentlicht.
La fiebre del mundial por estos días, ha contagiado a millones de personas en el mundo entero. El éxito inesperado de algunas selecciones de fútbol, ha contribuido en gran medida a este aumento de interés, pero también lo han hecho el alto nivel de competencia, la intensa pasión de los
On July 24, 10am ET, Stavros Asimakopoulos delivers the next installment of the Foresight/SAS Webinar Series, "Forecasting 'In the Pocket': Mobile Devices Can Improve Collaboration." Based on his article (co-authored with George Boretos and Constantinos Mourlas) in the Winter 2014 issue of Foresight, Stavros will discuss how smartphones, tablet computers
A SAS customer showed me a SAS/IML program that he had obtained from a book. The program was taking a long time to run on his data, which was somewhat large. He was wondering if I could identify any inefficiencies in the program. The first thing I did was to
I want to use SAS’ recent announcement of our Cost and Profitability Management solution as an opportunity to highlight an often overlooked but valuable application of activity-based costing: business process reengineering. But first, just a brief description of Cost and Profitability Management’s new breakthrough capability: In-memory model calculation. SAS’ decision
Principle 13: Remedial actions and supervisory measures - Supervisors should have and use the appropriate tools and resources to require effective and timely remedial action by a bank to address deficiencies in its risk data aggregation capabilities and risk reporting practices. Supervisors should have the ability to use a range
Last week I showed how to use the SUBMIT and ENDSUBMIT statements in the SAS/IML language to call the SGPLOT procedure to create ODS graphs of data that are in SAS/IML vectors and matrices. I also showed how to create a SAS/IML module that hides the details and enables you
The BFD blog probably won't make you the best forecaster you can be. There are plenty of books and articles and world class forecasting researchers (many of them meeting next week in Rotterdam at the International Symposium on Forecasting), that can teach you the most sophisticated techniques to squeeze every last
My last blog post showed how to simulate data for a logistic regression model with two continuous variables. To keep the discussion simple, I simulated a single sample with N observations. However, to obtain the sampling distribution of statistics, you need to generate many samples from the same logistic model.
Go USA! Go Germany! Go Mexico! Go Colombia! Wish you were still in it, England! That’s right, it’s World Cup time, and due to the international flavor of my family, I’ve got a number of teams I’m rooting for. I played a little soccer (or “futbol” in our house) back
In the energy industry, oil and gas companies as well as utilities are struggling with many changes at once. First, they're facing what the oil and gas industry has coined "the big crew change," meaning the retirement of those with the most skills and experience on how to run their
Data science, as Deepinder Dhingra recently blogged, “is essentially an intersection of math and technology skills.” Individuals with these skills have been labeled data scientists and organizations are competing to hire them. “But what organizations need,” Dhingra explained, “are individuals who, in addition to math and technology, can bring in
Did you check your email and/or favourite social media site before leaving for work this morning? Did you do it before getting out of bed? Don’t worry, you’re not alone. I do it every morning as a little treat while I “wake up” and whether I realize it or not,
In my book Simulating Data with SAS, I show how to use the SAS DATA step to simulate data from a logistic regression model. Recently there have been discussions on the SAS/IML Support Community about simulating logistic data by using the SAS/IML language. This article describes how to efficiently simulate
I speak with executives in every industry – in companies big and small – and they all have the same challenge: They’re overwhelmed with data. The problem? There’s a huge gap between the amount of data they possess and the number of employees who can analyze it. This lack of
