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
You’re walking around the bookstore at SAS Global Forum, looking at the new books and upcoming titles. There are lots of titles that look helpful, and a couple that are on your must-have list. You see SAS users and students eagerly talking with the authors, treating them like rock stars.
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
This morning, a fairly strong earthquake struck southern Mexico - can SAS analyze past earthquake data to help predict future earthquakes?... I don't have any pictures of earthquake damage, but here's one I took of the main house/prop from the Snow Camp Outdoor Theatre here in North Carolina - I imagine this
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
Everyone is intrigued by natural disasters - can we predict the likelihood of multiple disasters happening simultaneously?... My friend Rochelle is an avid SCUBA diver - here's a photo of a shark she got to 'smile for a picture' on a recent dive trip: Rochelle was asking if I could use SAS to
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
There are many factors that go into creating the next advanced analytics products at SAS, but Radhika Kulkarni, Vice President of Advanced Analytics told me there’s one main driving force. I caught up with her at the Analytics 2014 conference to talk more about advanced analytics and what products you
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
The old saying KISS (Keep It Simple) can be applied to just about anything, including sports analytics. Here I use SAS to create some simple charts to analyze a winning soccer team... To get you into the right mood, here is a picture of my friend Jennifer's dog, who loves soccer :) In
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
