Plotting population projections, with a confidence interval
During the year 2020, many countries and areas will be conducting their decennial census, and making projections to estimate what their population will be in the future. Therefore I decided to dust off one of my old SAS/Graph samples based on the 2010 census, and rewrite it using more modern
How data science can accelerate outcomes for the public sector
UK government departments and the wider public sector are under huge pressure to improve service delivery and efficiency. We also know that investments in data analytics and data science play a key role in transforming services to help citizens. So what are the key challenges preventing more widespread adoption of
The geometry of multivariate versus univariate outliers
An important concept in multivariate statistical analysis is the Mahalanobis distance. The Mahalanobis distance provides a way to measure how far away an observation is from the center of a sample while accounting for correlations in the data. The Mahalanobis distance is a good way to detect outliers in multivariate
Transformation in Nordic banking
Deloitte’s 2019 Banking and Capital Markets Outlook begins by stating that “a decade after the crisis, the banking industry is on firmer ground.” Shortly after it asserts that “there may be no better time than now to reimagine digital transformation.” Having tinkered at the margins to keep the lights on,
The marketing best practices that drive student and financial value in higher education
In my previous post, “Why personalising the student experience is critical to higher education’s viability," we examined the role customer intelligence can play in driving value for universities and students across the higher education journey. Specifically, analytics has a vital role to play in helping decision makers, particularly marketers, to
Persistent memory: one way to rein in IT costs
As data volumes continue to surge (with no signs of slowing down), the cost to handle all that data can have a very real impact on IT budgets. But for all the talk of the growing value of data, the cost side of the equation is often overlooked. After all,
Building a YOLO object detection model using SAS
Computer vision is one of the most sought-after artificial intelligence (AI) applications today, finding a wide variety of use cases in image recognition, object detection, biomedical assessment, and more. SAS supports a diverse set of AI and deep learning capabilities that can be used in many of these applications. One
6 tech influencers to follow on Twitter
My favorite tech influencers teach, ask questions and share their knowledge freely. They value quality over quantity, and they engage with each other authentically. My goals on social media are to learn, engage with the world socially, and to share what I think is cool – sometimes this is about
Calling SAS Decision Manager Rulesets in Event Stream Processing
SAS Decision Manager enables you to build and test decisions to use in batch processes, real-time web applications or with SAS Event Stream Processing. In this blog, I explain how to use Rulesets in an Event Stream Process project. If you are streaming data using SAS Event Stream Processing and
Is there more flooding than usual this year?
Flooding has been in the news the past few days, and that makes me want to analyze some data! I hang out at Jordan Lake (here in central North Carolina) a lot, so I decided to download the data for that lake, and do a graphical analysis. If you're interested
Truncate response surfaces
An analyst was using SAS to analyze some data from an experiment. He noticed that the response variable is always positive (such as volume, size, or weight), but his statistical model predicts some negative responses. He posted the data and asked if it is possible to modify the graph so
Give yourself the gift of Respite Care
We are in the midst of our third Powerful Tools of Caregiver class offering, and I am reminded again of the importance of self care for caregivers. As primary caregivers, it is likely you will experience higher degrees of stress, exhaustion, and are more prone to illness. It is important
How deadly was the flu in 2019?
Here in the US, there's a lot of talk about the flu each year. First, people discuss whether or not to get the flu shot. Then there are discussions about whether or not you or your friends have the flu (or something else). Then the discussions about what strain of
Interpolation vs extrapolation: the convex hull of multivariate data
Statisticians often emphasize the dangers of extrapolating from a univariate regression model. A common exercise in introductory statistics is to ask students to compute a model of population growth and predict the population far in the future. The students learn that extrapolating from a model can result in a nonsensical
How to view or create ODS output without causing SAS® to stop responding or run slowly
SAS makes it easy for you to create a large amount of procedure output with very few statements. However, when you create a large amount of procedure output with the Output Delivery System (ODS), your SAS session might stop responding or run slowly. In some cases, SAS generates a “Not
Demo of deep learning to detect tumors in liver CT scans
This is the fifth and final post in my series of posts about the deep learning model I developed to detect tumors in 3D CT scans of livers. My last post talked about visualizing the results of the computer vision project. This post will cover model accuracy and the final
US ethanol fuel production - a beautiful graph!
US farmers grow a lot of food ... but did you know some of them also grow fuel for our vehicles? Follow along and you'll learn how much fuel they grow, and also learn some tips about plotting this type of data! These days most gasoline in the US has
Puzzle obsession ... piecing together a 360-degree view of a patient.
I am obsessed with jigsaw puzzles. Specifically, 1000-piece mystery puzzles, entertaining not just for their pictorial humor, but also for the challenge. Unlike traditional puzzles, you don't know what you are putting together because the completed puzzle isn't pictured on the box. Mystery puzzles are constructed so that you must
SAS deep learning with Python made easy using DLPy
I look forward to Pi Day every year at SAS because it's a day of celebration including yummy pies and challenging games that challenge you to recall the digits after the decimal point in Pi. Plus you get to wear Pi t-shirts (I have about seven). Today, though we are going to talk about DLPy which sounds like Pi and
It’s a game changer: Sports analytics in higher education
Why is sports analytics rapidly becoming a high priority for several universities? Because they’re beginning to truly understand the significance of a winning athletic program. The value of a win speaks volumes and takes on different forms. It trickles down to the fans filling the stadium seats, television contracts, fan
Beyond Food: What a Dietitian Can Do For You
Today is Registered Dietitian Nutritionist Day- a day to celebrate the dedication of dietitians as advocates for advancing the nutritional health of people around the world. I personally chose to become a Dietitian so that I could empower people by giving them knowledge and tools to optimize their total
The value of pi depends on how you measure distance
It's time to celebrate Pi Day! Every year on March 14th (written 3/14 in the US), math-loving folks celebrate "all things pi-related" because 3.14 is the three-decimal approximation to the mathematical constant, π. Although children learn that pi is approximately 3.14159..., the actual definition of π is the ratio of
Data stewardship for artificial intelligence
Jim Harris says curating AI’s curriculum is the responsibility of data stewards.
5 ways analytics is used at the Special Olympics
The Special Olympics is part of the inclusion movement for people with intellectual disabilities. The organisation provides year-round sports training and competitions for adults and children with intellectual disabilities. In March 2019 the Special Olympics World Games will be held in Abu Dhabi, United Arab Emirates. SAS is an official
How to detect SAS data sets that contain (or do not contain) character variables
A SAS programmer posted an interesting question on a SAS discussion forum. The programmer wanted to iterate over hundreds of SAS data sets, read in all the character variables, and then do some analysis. However, not every data set contains character variables, and SAS complains when you ask it to
