Sports provide us with many familiar clichés about playing defense, such as: Defense wins championships. The best defense is a good offense. Or my favorite: The best defense is the one that ranks first statistically in overall defensive performance, after controlling for the quality of the offenses it has faced. Perhaps not
After the legalization of recreational marijuana use in Colorado in 2012, it has been a much more frequent news topic than before - even from a data analysis perspective... I was recently looking for 'interesting' data to analyze with SAS, and I noticed some articles about the increasing potency of marijuana in
SAS procedures usually handle missing values automatically. Univariate procedures such as PROC MEANS automatically delete missing values when computing basic descriptive statistics. Many multivariate procedures such as PROC REG delete an entire observation if any variable in the analysis has a missing value. This is called listwise deletion or using
Smallpox was declared eradicated in 1979, after an extensive vaccination campaign in the 19th and 20th centuries. This blog post contains a visual analysis of the final years of this disease in the US ... In my previous blog post, I imitated and improved infectious disease graphs from a recent Wall
It's that time of year: Awards season. While we on the SAS Social Media Team will be happily following along this Sunday for the 87th Annual Academy Awards (via Twitter, naturally), we thought it only appropriate to use this as a time to celebrate our customers in social from 2014. From

Hadoop is increasingly being adopted as the go-to platform for large-scale data analytics. However, it is still not necessarily clear that Hadoop is always the optimal choice for traditional data warehousing for reporting and analysis, especially in its “out of the box” configuration. That is because Hadoop itself is not
The Institute of Business Forecasting's FVA blog series continued in January, with my interview of Shaun Snapp, founder and editor of SCM Focus. Some of Shaun's answers surprised me, for example, that he doesn't compare performance to a naïve model (which I see as the most fundamental FVA comparison). But he went
How many of us have heard or even said the phrase, "If it's not broke, don't fix it." While on rare occasions this may be the correct approach, it is a statement that stops innovation and creativity in its tracks. You might as well say, "Because we've always done it that
Another Valentine's Day has passed. I often wonder where the time goes. It seems like yesterday my daughter was buying those little cards and sharing cut out hearts with her peers. Now, she's 15 and this year she had fun in a different way and I was happy to be
La analítica de negocios se ha convertido en la solución ideal para empresas de los diversos sectores económicos, sin embargo, ha llegado el momento de que los países se apropien y lleven a cabo nuevos planes de profundización, especialización y educación en este campo. Ya no basta con saber que
Many larger SAS deployments have multiple instances of similar SAS-related servers. For example, a distributed SAS Enterprise BI environment may have several machines running instances of the object spawner or the OLAP server. Similarly, all of your distributed SAS Visual Analytics deployments have worker nodes that are typically dedicated Linux
The Wall Street Journal recently published some graphs about seven infectious diseases, and I tried using SAS to improve the graphs ... it's a veritable infectious disease (graph) bake-off! Let's start with Measles ... here's a screen-capture of WSJ's measles graph: In general, their graph is eye-catching, and I learned a lot
