Cases of the measles have certainly been making headlines in the news recently. And with all the data at our disposal these days, it seems like we should be able to predict which areas in the US are most likely to have measles outbreaks, eh? A group of independent researchers
When it comes to meals, how often do you find yourself pressing the easy button? If you are on a first name basis with the fast food drive-through checkout person or if the frozen pizzas boxes are starting to pile up, keep reading.
"There's a way to do it better - find it." - Thomas A. Edison When it comes to SAS coding, this quote by Thomas A. Edison is my best advisor. Time permitting, I love finding better ways of implementing SAS code. But what code feature means “better” – brevity, clarity
SAS/STAT software contains a number of so-called HP procedures for training and evaluating predictive models. ("HP" stands for "high performance.") A popular HP procedure is HPLOGISTIC, which enables you to fit logistic models on Big Data. A goal of the HP procedures is to fit models quickly. Inferential statistics such
In his article How to use CASL to develop and work with user-defined CAS actions, Brian Kinnebrew defines CASL as "a language specification used by the SAS client to interact with and provide easy access to Cloud Analytic Services (CAS). CASL is a statement-based scripting language with many uses and
In this post I wanted to bring attention to the book Adult Children of Emotionally Immature Parents: How to Heal from Distant, Rejecting, or Self-Involved Parents. Of the 2,000+ books that are in our Work/Life Library, this is a book that I refer to most often. I continue to receive
In short, digital transformation concerns competition, speed, quality and costs. In the current connected world, the consumer has a lot of choices and is also less bound to a single provider. The customer expects immediate answers to rely on. Will someone wait two weeks for a loan approval, or will
If you're curious what makes SAS a great workplace, one answer always rises to the top - our people. It's no secret that the people who work here are some of the best and brightest - not to mention the most passionate, accountable, authentic and curious people you'll ever meet. And at SAS, Your
Everyone is talking about artificial intelligence. Unfortunately, a lot of what you hear about AI in the movies and on the TV is sensationalized for entertainment. Indeed, AI is overhyped. But AI is also real and powerful. Consider this: engineers worked for years on hand-crafted models for object detection, facial
When fitting a least squares regression model to data, it is often useful to create diagnostic plots of the residuals versus the explanatory variables. If the model fits the data well, the plots of the residuals should not display any patterns. Systematic patterns can indicate that you need to include
If you've been teaching for more than a few weeks you have already begun the process of collecting, curating, and sharing lessons, resources, and tools that engage your students and support your curriculum. But how to collect all of these various materials in one place, in a format that engages
For every project in SAS®, the first step is almost always making your data available. This blog shows you how to load three of the most common input data types—a data set, a text file, and a Microsoft Excel file—into SAS® Cloud Analytic Services (CAS) tables. The three methods that
One of my favorite bloggers (Grown and Flown) recently wrote about the “Seven Signs of the Aging Apocalypse” – or those inevitable indicators that we are aging. Recently, as my brothers and I were planning my Dad’s 80th birthday and we were trading hilarious “Dad-isms” that would eventually become a
Move over video games and sports. Make room for escape rooms. This burgeoning form of entertainment found its roots in the video gaming movement. Escape rooms tap into a player's drive to reach the next level, solve a puzzle and win. Escape rooms present a physical game that traps you
My last blog post discussed the applications of AI in retail and how retailers were starting to use solutions like image recognition to improve customer experience. However, implementing AI is not without its challenges. This post continues the conversation with Shailesh Jain, Group Head of Analytics at Landmark Group, about
If you're curious what makes SAS a great workplace, one answer always rises to the top - our people. It's no secret that the people who work here are some of the best and brightest - not to mention the most passionate, accountable, authentic and curious people you'll ever meet. And at
As the sharing economy grows, you can catch a ride on Uber, have meals delivered by Grubhub ... and even stay in someone else's house (rather than a hotel) via sites like Airbnb. And speaking of that last one, I recently read an article listing Airbnb's top 20 'wish-listed' homes
A previous article describes the DFBETAS statistics for detecting influential observations, where "influential" means that if you delete the observation and refit the model, the estimates for the regression coefficients change substantially. Of course, there are other statistics that you could use to measure influence. Two popular ones are the
As a data scientist, did you ever come to the point where you felt the need for an evolved analytics platform bringing together the disparate skills of open source and commercial software? A system that can enable advanced analytic capabilities. This is now possible and easy to implement. With many
Major European football (soccer) leagues came to an end after an intensive year. Manchester City claimed the Premier League title after a high-intensity title race against Liverpool. It is unbelievable that Liverpool would have won 25 out of the last 27 PL titles with 97 points. Luckily, the Reds
What is Item Response Theory? Item Response Theory (IRT) is a way to analyze responses to tests or questionnaires with the goal of improving measurement accuracy and reliability. A common application is in testing a student’s ability or knowledge. Today, all major psychological and educational tests are built using IRT.
David Loshin suggests that reference data could be the foundation of future governance structures.
Is your life philosophy putting you on the path to success? Vice President for US Government, Grant Brooks’ philosophy is doing just that. It guides every facet of his life. Focusing on significance will lead to success “For as long as I can remember, I have carried this deeply held
My article about deletion diagnostics investigated how influential an observation is to a least squares regression model. In other words, if you delete the i_th observation and refit the model, what happens to the statistics for the model? SAS regression procedures provide many tables and graphs that enable you to
In these modern times, my utility bill has a bar chart so I can see how my current consumption compares to my historical usage. I decided to create my own version of this utility bill bar chart, and make a few improvements along the way. If you're into SGplot bar
If you're curious what makes SAS a great workplace, one answer always rises to the top - our people. It's no secret that the people who work here are some of the best and brightest - not to mention the most passionate, accountable, authentic and curious people you'll ever meet.
In this 'Rosetta Graph' example, I demonstrate how to control bar chart colors in Gchart and SGplot. But first, here's a little diversion... some artwork in my office here at SAS. There's a *lot* of artwork hanging around at SAS, but this particular painting wasn't created by the SAS artists
It’s that time of year again — picnics, parties, and backyard cookouts. The smells of summer are starting to permeate the air — fresh cut grass, honeysuckles, sunscreen, and the aroma your neighbors’ dinner floating from their grill into your nose.
For linear regression models, there is a class of statistics that I call deletion diagnostics or leave-one-out statistics. These observation-wise statistics address the question, "If I delete the i_th observation and refit the model, what happens to the statistics for the model?" For example: The PRESS statistic is similar to
(Editor's note: Megan Bobroske is a second grade teacher at Denver's Bradley International School) Coding was a brand new experience for my second graders. Prior to using CodeSnaps, a free coding app from Curriculum Pathways, a few of them had participated in an after-school coding club, and another handful had
