Decision trees are one of the top machine learning algorithms used by data scientists. Decision trees use supervised learning to classify problems. Even if you are not a data scientist, chances are you can interpret the visual output from a decision tree.
I previously wrote about how to understand standardized regression coefficients in PROC REG in SAS. You can obtain the standardized estimates by using the STB option on the MODEL statement in PROC REG. Several readers have written to ask whether I could write a similar article about the STDCOEF option
I caught up with Mark Schneider, Advisory Product Manager here at SAS, about the future of SAS Grid and SAS Viya.
Here in the US, the pipeline which supplies gasoline to North Caroline (and much of the southeast) was hacked, and had to be shut down for several days. This caused gasoline shortages, and long lines at the gas pumps (as shown in the picture below, by my friend Daniel). But
It’s not too late to register for Tuesday’s (May 18) SAS Global Forum kickoff. And there are so many online sessions it’s going to be hard to choose which to attend. Business and analytics experts are leading dozens of virtual session for industries, from agtech, banking and financial services, goverment,
Lake Superior is the largest freshwater lake (by surface area) in the world. And its largest island is Isle Royale. And its largest lake is Lake Siskiwit. And its largest island is Ryan Island. Ryan Island's largest (seasonal) pond is called Moose Flats. And it contains an 'island' (or a
It’s almost time for another SAS Global Forum, and this year even I’m surprised by the range of topics and experiences available for attendees. With the conference theme of “New day, new answers, inspired by curiosity,” you probably guessed we’ll be talking about analytics and pandemic recovery. And, of course,
The COVID-19 pandemic forced government agencies to accelerate digital transformation efforts, and the Internal Revenue Service (IRS) was no exception. The IRS was already in a significant transition period, spurred by the Taxpayer First Act, which was signed into law in July 2019. The Act was designed to improve the
The basic sheet pan never ceases to amaze me. It’s a kitchen essential I couldn’t live without and continues to revolutionize the way I prepare meals for my family. Yes, it’s great for one pan meals (hands-off cooking and simple clean up, sign me up!) but it can also do some
You can standardize a numerical variable by subtracting a location parameter from each observation and then dividing by a scale parameter. Often, the parameters depend on the data that you are standardizing. For example, the most common way to standardize a variable is to subtract the sample mean and divide
With my collaborators Len Tashman (Editor of Foresight) and Udo Sglavo (VP of Analytics R&D at SAS), we are happy to announce the release of our new collection, Business Forecasting: The Emerging Role of Artificial Intelligence and Machine Learning (Wiley, 2021). Building upon our previous collection Business Forecasting: Practical Problems and
The 10th edition of this series puts the spotlight on two organizations at which I had the pleasure of helping to teach students the humble beginnings of data, analytics and data visualization: Avans and HAN (Hogeschool van Arnhem en Nijmegen). My sources for this post are Gerben Muller, who initially
It’s safe to say that SAS Global Forum is a conference designed for users, by users. As your conference chair, I am excited by this year’s top-notch user sessions. More than 150 sessions are available, many by SAS users just like you. Wherever you work or whatever you do, you’ll
Early in her career, a mentor gave Dawnté Early some career advice that would ultimately change her life. “If you can learn how to analyze and dig into your own data, instead of paying others to do it for you, you’ll be able to do your own research and write
Odani's truism is a mathematical result that says that if you want to compare the fractions a/b and c/d, it often is sufficient to compare the sums (a+d) and (b+c) rather than the products a*d and b*c. (All of the integers a, b, c, and d are positive.) If you
I think one of the great uses of analytics and graphics is to show things like cancer clusters on a map. There are many factors that can lead to a higher incidence of diseases in geographical areas, and chemicals are often the culprit. For example, paraquat has been potentially linked
If there’s one thing that we’ve learned from working from home, it’s the value of wellness. Not leaving our homes for work has collectively meant less steps (aka daily activity), easy access to the family fridge, and blurred lines between work and home life…and even the days for that
Dr. Ayesha Khanna has a vision for blending our physical infrastructures with cloud and AI infrastructures to improve the way we live, work and learn. As the co-founder and CEO of ADDO AI, an AI solutions firm and incubator, she advises corporations and governments on AI and smart cities. She
Break down silos, uncover problems, support mental health solutions – with data and analytics.
Set it and forget it. That’s how SAS Viya Jobs and Flows should work, right? Well, just like most other things in life, it’s not that simple. What if you have multiple Jobs set to run in a Flow and one fails? Do you exit the process or continue with
Quick! Which fraction is bigger, 40/83 or 27/56? It's not always easy to mentally compare two fractions to determine which is larger. For this example, you can easily see that both fractions are a little less than 1/2, but to compare the numbers you need to compare the products 40*56
By Paul Ridge, Head of Insurance, SAS UK & Ireland Black swan events are not unknown to the insurance industry. Whether it’s natural disasters such as the Japanese earthquake in 2011, the Chernobyl disaster in 1986 or pandemics such as the SARS virus in 2002. By their nature, these kinds
An estimated 44% of people in jail and 37% of those in prison have a mental health condition. When I worked at the San Bernardino County Department of Behavioral Health, the Sheriff and Probation Departments were close partners with us. My Research & Evaluation team worked with their data teams to evaluate
A previous article discusses the definition of the Hoeffding D statistic and how to compute it in SAS. The letter D stands for "dependence." Unlike the Pearson correlation, which measures linear relationships, the Hoeffding D statistic tests whether two random variables are independent. Dependent variables have a Hoeffding D statistic
Every 10 years the United States conducts a Census where we count all the people. This week the 2020 Census population totals for each state were released. And how might these numbers affect you? ... One thing the Census numbers are used for is to determine how many of the
With the release of SAS Viya 2020.1.4, text categories and concept models can now be deployed into production with just a few clicks and used to score data in-batch and via API! You can also now use these models in decision flows.
Cindy Wang's curiosity about the Mandelbrot set led her to draw one using SAS Visual Analytics.
Data, AI and digital transformation will define the industry of the future. The die is cast. Without an industrial approach for analytics, there will be no future! Diamonds are forever Khepri, a deity of ancient Egypt, symbolized the morning rebirth of the sun. Khepri is also said to have inspired
Exercise and nutrition go hand-in-hand, and there is lots of conflicting advice out there about the best way to eat to power your workouts. If you’re just getting started, or getting back in the game after a fitness hiatus it’s important to separate the hype from tried and true tactics.
There are many statistics that measure whether two continuous random variables are independent or whether they are related to each other in some way. The most well-known statistic is Pearson's correlation, which is a parametric measure of the linear relationship between two variables. A related measure is Spearman's rank correlation,
