See how to sample unstructured (text) data using SAS Viya and CAS actions. This post includes complete code to cluster the text documents via k-means, and treats the cluster memberships as strata for analysis.
I have lived in the Town of Cary for more than twenty years; two of my three children were born at the local WakeMed Cary Hospital. I’m a big fan of my city, or town as it prefers to be called – even though the population is over 160,000. That’s
More than 3.5 percent of the world’s population is on the move, considered international migrants. That’s more than 250 million people living in a country different than their country of birth or nationality. To put that another way, if all migrants lived in a single country, their population would be
I've said it before: spreadsheets are not databases. However, many of us use spreadsheets as if they were databases, and then we struggle when the spreadsheet layout does not support database-style rigor of predictable rows, columns, and variable types -- the basic elements we need for analytics and reporting. If
Jim Harris says the GDPR may cause seismic changes in how people think of privacy and personal data.
Many things in nature can be seen as chain reactions. When one action occurs, others follow suit. For example, atmospheric greenhouse gas levels are increasing, which leads to a warming of the oceans. As the oceans warm, weather and climate patterns across the globe are impacted because the amount of
This article shows how to construct a butterfly plot in SAS. A butterfly plot (also called a butterfly chart) is a comparative bar chart or histogram that displays the distribution of a variable for two subpopulations. A butterfly plot for the cholesterol readings of 5,057 patients in a medical study
Open data is critical to research, particularly at universities. The many university students that attend SAS Global Forum bring an energy and vitality to the conference that is unmistakable. They’re everywhere…in sessions, social activities, out on the town and, of course, the academic events. This year, 150 of them graced
In a previous blog post, I discussed ways to produce statistically independent samples from a random number generator (RNG). The best way is to generate all samples from one stream. However, if your program uses two or more SAS DATA steps to simulate the data, you cannot use the same
I have good news to share about the future. Despite what you may have heard elsewhere, the future of work in a world with artificial intelligence (AI) is not all doom and gloom. And thanks to a research-backed book from Malcolm Frank, What to Do When Machines Do Everything, we
Landmark population health study involving 50,000 northern Nevadans turns to SAS to reveal hidden health insights These are exciting times in health care. Earlier this week I read that the NIH will soon open enrollment for its “All of Us” initiative. The research program aims to compile the genetic and health
When you ask Mark Yost about what he does at SAS every day, his eyes light up. Mark’s our Assistant Manager for Food Services at SAS, but he’s so much more than that. He’s a champion for diversity and a leader who empowers his team to be the same. For
A future of flying cars and Minority Report-styled predictive dashboards may still be some time away, but the possibilities of robotics and Artificial Intelligence (AI)-powered automation are a reality today. From connected cars to smart homes and offices, we see daily how big data and the Internet of Things (IoT)
You've probably heard about the "80-20 Rule," which describes many natural and manmade phenomena. This rule is sometimes called the "Pareto Principle" because it was discovered by Vilfredo Pareto (1848–1923) who used it to describe the unequal distribution of wealth. Specifically, in his study, 80% of the wealth was held
SAS® supports the creation of deep neural network models. Examples of these models include convolutional neural networks, recurrent neural networks, feedforward neural networks and autoencoder neural networks. Let’s examine in more detail how SAS creates deep learning models using SAS® Visual Data Mining and Machine Learning. Deep learning models with
A colleague and I recently discussed how to generate random permutations without encountering duplicates. Given a set of n items, there are n! permutations My colleague wants to generate k unique permutations at random from among the total of n!. Said differently, he wants to sample without replacement from the
SAS has never been able to sit idle and watch from the sidelines as crises ensue. Why? Because we know that good can be made possible if data is put to work. SAS Global Forum opening session spotlighted four real-life examples of how SAS is showing up and improving the
Data and analytics touch our lives every day. Consider: A call from your bank warning of a suspicious transaction. A well-timed discounted offer for something you need. Most people realize that data and analytics are behind these things, but they remain on the periphery of mainstream conversations. We need to
If you won’t be in Denver, stay engaged to everything happening through the SAS Global Forum 2018 Virtual Event. With content streaming live from opening session, tech connection, tech talks and a few breakout sessions, you’re sure to find something you love. And don't forget to join the conversation on social media.
In the extended enterprise, data integration challenges abound. David Loshin explains.
Gradient boosting is one of the most widely used machine learning models in practice. See how to use gradient boosting model for classification in SAS Visual Data Mining and Machine Learning.
Generating HTML output might be something that you do daily. After all, HTML is now the default format for Display Manager SAS output, and it is one of the available formats for SAS® Enterprise Guide®. In addition, SAS® Studio generates HTML 5.0 output as a default. The many faces of
One of my favorite magazines, Significance, printed an intriguing image of a symmetric matrix that shows repetition in a song's lyrics. The image was created by Colin Morris, who has created many similar images. When I saw these images, I knew that I wanted to duplicate the analysis in SAS!
Jim Harris considers the technical infrastructure challenges of data preparation for streaming data.
A dual response axis chart is useful when the data type for the multiple measures are not compatible. For example, when overlaying measures like "This Year" sales with "Last Year" sales, the format and magnitudes of the two measures (or values for two groups) may be compatible, and it is
Can you use a data visualization tool to display building maps, floor designs and other Esri data? With the recent addition of custom polygon support in SAS Visual Analytics 8.2, customers wondered if this feature can be utilized to render different types of regional overlays. A common request is to
For the last two years, I’ve spent time listening to and brainstorming with automakers, their suppliers and other technology companies about how to monetize connected vehicle data. This involves: Data that’s offloaded from a roving vehicle fleet (cars, trains, semi-trucks, farm tractors, you name it!). Data coming from driving-related mobile apps used
I wrote more than 100 posts for The DO Loop blog in 2017. The most popular articles were about SAS programming tips, statistical data analysis, and simulation and bootstrap methods. Here are the most popular articles from 2017 in each category. General SAS programming techniques INTCK and INTNX: Do you
It's that time of year, once again, when I take a traditional Christmas song or carol and create a fun technology-related version of it to share with all of you. This is the fourth year and the seventh song, so I hope you enjoy your holiday song for 2017: AI
A steady drumbeat of news coverage makes one thing clear: Opioid abuse is rising and has reached epidemic levels throughout our country. Overdoses from the diversion and abuse of prescription opioids are one cause of the surge in deaths. Overdoses from heroin and other illicit synthetic opioids (such as heroin,
