I remember the first time I used PROC GLM in SAS to include a classification effect in a regression model. I thought I had done something wrong because the parameter estimates table was followed by a scary-looking note: Note: The X'X matrix has been found to be singular, and a
Yesterday I heard someone recount a story of arriving to a show only to realize their tickets were for the next week. As I heard this story, I had flashbacks to Thanksgiving a few years ago, arriving to a vacation rental home on the wrong week. I wrote a post
Jim Harris says data stewards are essential to analytics, providing life cycle management for data across the enterprise.
The 6th maintenance release of SAS 9.4 is now available for users. Along with it comes a new SG procedure - the SGPIE procedure (pre-production). The primary audience for the SG procedures has been the analytical user, for creating effective displays of analytical data. However, the rich feature set of these
Do you remember The Matrix movies, that started coming out in 1999? Hopefully this movie franchise didn't give you a fear of virtual reality and AI. The thing I remember most from the movie was the really cool slow-motion video effects (from multiple angles) in the fight scenes. And the
Joseph Woodside discusses the evolution of digital transformation in healthcare in three eras.
Today, we’re talking about the Match.com of the corporate world: LinkedIn. Love it or hate it, LinkedIn is essential for making professional connections and, ultimately, getting hired. According to a CareerBuilder survey, 70% of recruiters say they use social media channels to research candidates online. And what you have on
Last week my colleague, Robert Allison, visualized data regarding immunization rates for kindergarten classes in North Carolina. One of his graphs was a scatter plot that displayed the proportion of unimmunized students versus the size of the class for 1,885 kindergarten classes in NC. This scatter plot is the basis
This week I noticed that they've started building the lot where they sell Christmas trees near SAS (at the intersection of Maynard & Reedy Creek Rd). They put up a nice rustic wooden fence, and lights, and maybe even a fire pit to keep their workers warm. They sell some
Burger and fries, wine and cheese, peanut butter and jelly … some things just go better together. For organizations embarking on digital transformation, AI and IoT just go better together. These two distinct technologies; AI and IoT (or AIoT) are a natural fit. To take an analogy from the human
A data analyst asked how to compute parameter estimates in a linear regression model when the underlying data matrix is rank deficient. This situation can occur if one of the variables in the regression is a linear combination of other variables. It also occurs when you use the GLM parameterization
As we move into the Thanksgiving holiday and celebrate #givingTuesday, it’s a perfect time to reflect on thankfulness. The attitude of gratitude is enriching and has been shown to have many benefits. I use this approach often as I teach a variety of wellness classes. Although I practice what I
I recently read an article that said a school in Asheville, North Carolina had the worst chickenpox outbreak in the state in 2 decades. The article was interesting, and it also let me know I had a hole in my knowledge ... "What?!? - There's a chickenpox vaccine?!?" When I
Starting with SAS 9.4M6, procedures that used to be provided with a SAS/GRAPH installation are now available with Base SAS. Using these procedures along with PROC SGMAP can help you create some very nice maps. This blog builds on previous posts and highlights the: MAPSSAS Data Sets GREMOVE procedure %CENTROID
What is object detection? Object detection, a subset of computer vision, is an automated method for locating interesting objects in an image with respect to the background. For example, Figure 1 shows two images with objects in the foreground. There is a bird in the left image, while there is a dog
Data management gets lost in the enthusiasm around Artificial intelligence (AI) and machine learning (ML). Not surprising, when it's an algorithm that decides what search results to show you, guides the self-driving cars on the roads, and powers the anti-fraud bots that monitor every credit card transaction we make. Charles
Reconsider conventional assumptions about data governance – three suggestions for chief data officers.
SAS was again named a Top 10 Place to Work in the World by Great Places to Work™. This is quite an honor, and one which SAS has enjoyed for the past eight years. SAS has also been a highly ranked work place in the US for the past 20
You might know that you can use the ODS SELECT statement to display only some of the tables and graphs that are created by a SAS procedure. But did you know that you can use a WHERE clause on the ODS SELECT statement to display tables that match a pattern?
Healthcare fraud is alive and well. Honesty is dead and gone. There, I’ve said it. What else are we to take from surveys that find that 27% of people would sell their work passwords...44% of them for less than $1,000?* What does it mean that 37% of survey respondents think
Disclaimer: this article does not cover or promote any political views. It’s all about data and REST APIs. I am relieved, thankful, elated, glad, thrilled, joyful (I could go on with more synonyms from my thesaurus.com search for 'happy') November 6, 2018 has come and gone. Election day is over.
A few days back I published an article on including more subject data in a Waterfall graph. This was motivated by the desire from many users to view more data in the same graph, thus avoiding the need to refer to different graphs for the relevant information. In this case,
In my first two posts of this blog series, we heard why two students chose to pursue a STEM field and what appealed to them about data science. We also heard how they put their knowledge to work on a real-world data science project. Today, we'll hear their advice to future
There has been a lot of controversy surrounding this year's midterm election, when it comes to counting the ballots ... and I kept hearing the term provisional ballots in the news. But I'm embarrassed to say that I didn't really know much about provisional ballots. I decided to do a
When describing their business model, our customer, Epipoli (one of the leading gift card companies in Europe), tells the story of the ancient Limoncello makers of Italy. Limoncello is an intensely lemon-flavored liqueur famously produced in Sorrento, the Amalfi coast, and the island of Capri. The drink started as a local tradition, but quickly
The US 'midterm' elections have finally started to wind down, and we finally have some (mostly) finalized results to study. But what's the best way to visualize who won the US congressional seats in each of the 435 districts? Let's dive into this topic!... Preparation For starters, I couldn't find
JSON is a popular format for data exchange between APIs and some modern databases. It's also used as a way to archive audit logs in many systems. Because JSON can represent hierarchical relationships of data fields, many people consider it to be superior to the CSV format -- although it's
Joseph Woodside shares examples of applied experimental learning in healthcare from his book, "Applied Health Analytics and Informatics Using SAS".
Prior to distributed DATA Step, DATA Step programmers never had to think about achieving repeatable results because DATA Step ran single-threaded and the source SAS7BDAT dataset was stored on disk. But if you need to obtain repeatable results in DATA Step code that runs distributed in CAS, this post provides a workaround that you'll want to keep handy.
Teenagers. I have three boys, and two of them are teenagers. 15 year-old Kav is my middle son, and he gave me permission to share his story here. When he was five, Kav was diagnosed with Type I Diabetes, and I'm in awe of how he's accepted this challenging, lifelong
