Two of my colleagues have shared their experiences as a statistic and a child who could have been left behind. I too have my own story that helped drive my passion. All of us define equity in different ways. Equity is a concept that is hard to define, and we
For colleges and universities, awarding financial aid today requires sophisticated analysis. When higher education leaders ask, “How can we use financial aid to help meet our institutional goals?” they need to consider many scenarios to balance strategic enrollment goals, student need, and institutional finances in order to optimize yield and

Gate Pose (Sanskrit: Parighasana) Begin on mat kneeling with toes curled under and torso lengthened with crown reaching tall. Extend your right leg out to the right and press your entire foot into
As many of the regular readers of this blog know, SGPLOT and GTL, provide extensive tools to build complex graphs by layering plot statements together. These plots work with axes, legends and attribute maps to create graphs that can scale easily to different data. There are, however, many instances where
In an IoT world, everything is connected. But what does it mean to be connected? Does it mean being plugged in to your phone, car, home, TV, favorite apps and retailers? Does it mean knowing what’s happening all around you? And having the “things” you’re connected to acting as recommender
When building models, data scientists and statisticians often talk about penalty, regularization and shrinkage. What do these terms mean and why are they important? According to Wikipedia, regularization "refers to a process of introducing additional information in order to solve an ill-posed problem or to prevent overfitting. This information usually
In the fourth post of the 10 Commandments of Applied Econometrics series we discussed the issues of keeping the solutions sensibly simple and applying model validation. Today, I will present another commandment related to data mining techniques. Use data mining reasonably. In the econometric community, data mining is a controversial and highly emotional
Is this menopause? Maybe you've noticed some changes. Perhaps it’s the occasional hot flushed feeling that erupts like a volcano or maybe it's the irregular periods when you’ve always been like clockwork. Although menopause is often thought of as a singular event, it isn’t unless you are undergoing chemotherapy that
Helmut Plinke explains why modernizing your data management is essential to supporting your analytics platform.
A SAS customer asked how to use SAS to conduct a Z test for the equality of two proportions. He was directed to the SAS Usage Note "Testing the equality of two or more proportions from independent samples." The note says to "specify the CHISQ option in the TABLES statement
Tomorrow is Independence Day, a federal holiday in the United States. Flags are displayed everywhere, especially in Washington, D.C., where I live. So let's have a little Fun with Flags! The current U.S. flag has 50 stars, one per state, with five rows of six stars interleaved with four rows
When I arrived for a training course with the name, "Powerful storytelling for tech," I was surprised to discover that most of the attendees worked in sales, rather than the marketing and communications crowd I'd been expecting. They were all there to learn how best to engage prospects – how
If you spend a lot of time in SAS Enterprise Guide (as I do), you probably get to know its features pretty well. But we don't always take the time to explore as we should, so there might be a few golden nuggets of editor knowledge that have escaped you
My colleague, Lisa, and I were comparing notes the other day. Both of us starting working in our teens (14 and 15 respectively) during the academic year as well as the summers. I worked at Sears in the drapery and bedspread department. I’ll never forget my first boss—Mr. Arnold. He
The Kettlebell (KB) clean is a multi-joint movement that incorporates a squat, a pull, and shoulder rotation. You will work to maximize momentum generated in the lower body to use your upper body while challenging core stability. This exercise requires a little coordination and precision, so take your time learning
Students in introductory statistics courses often use summary statistics (such as sample size, mean, and standard deviation) to test hypotheses and to compute confidence intervals. Did you know that you can provide summary statistics (rather than raw data) to PROC TTEST in SAS and obtain hypothesis tests and confidence intervals?
As a technical consultant for SAS, I have the privilege of meeting with SAS customers, learning more about how they use our software, and then helping them solve their problems. Recently, a client of mine was having trouble finding a way to implement the use of multiple application servers in
We live in exciting times. Our relationships with machines, objects and things are quickly changing. Since mankind lived in caves, we have pushed our will into passive tools with our hands and our voices. Our mice and our keyboards do exactly as we tell them to, and devices like the
In this blog post I’d like to explore how to create a custom group in SAS Viya to restrict access to functionality. To illustrate my points, we will create a report developers custom group and ensure that only users of that group can create reports and analysis in SAS Visual Analytics.
Choosing great colors for a graph is sometimes the most difficult part. And here is yet another thing you need to worry about ... sometimes colors represent different things in different cultures! In this blog post, I improve a graphic to help you get a grasp on those color-to-culture relationships.
David Loshin discusses big data identity resolution in a programming and execution environment.
I'm sure I'm not the only one who has read and contributed to threads on the internet about all the different languages used for data mining. But one aspect that's been left out of most of these comparisons is that SAS is more than a 4th generation programming language (4GL).
In my last blog, we examined the data pane in SAS Visual Analytics 8.1. That blog discussed how to have the data pane display the data items of your active data source, and how to perform tasks such as viewing measure details, changing data item properties, and creating geographic data items,
One of the big benefits of SAS Viya is how approachable it is for programmers of other languages. You don't have to learn SAS in order to become productive quickly. We've seen a lot of interest from people who code in Python, maybe because that language has become known for
Many of the regulations coming into effect after 2010, are the result of the financial crisis that has significantly re-shaped the financial industry worldwide and especially in Europe. One of the major projects that has been undertaken by the statistics team of the ECB, launched in 2011, is the setup
The average American household spends about 12.5% of income on food, with a shrinking margin of difference between money spent on groceries and at restaurants (57% versus 43%). With over 1 million restaurant establishments in the United States, it’s no wonder that dining out is now the norm rather than
Suppose you roll six identical six-sided dice. Chance are that you will see at least one repeated number. The probability that you will see six unique numbers is very small: only 6! / 6^6 ≈ 0.015. This example can be generalized. If you draw a random sample with replacement from
Summer is here, which means vacations and time at the pool with a good book. If expanding your knowledge is a goal of yours this summer, SAS has a shelf full of new titles becoming available over the next few months. From new editions of classics – such as SAS® for Forecasting
I've found that when supporting others it can be helpful to simply normalize that it's ok to feel two things at once. Usually, one of the two is more "taboo". "Of course you are feeling disappointed by your friend's actions. Being disappointed doesn't mean you are not appreciative of the positive aspects of your friendship." "Of course you
Let me start by posing a question: "Are you forecasting at the edge to anticipate what consumers want or need before they know it?" Not just forecasting based on past demand behavior, but using real-time information as it is streaming in from connected devices on the Internet of Things (IoT).
