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,
Statewide longitudinal data systems (SLDS) have been around for many years, helping states understand students’ paths through the education system and beyond. The COVID-19 pandemic was an opportunity for one state’s SLDS to step up in new ways that helped feed children in need. With the US Department of Agriculture
Note from Gül Ege Sr. Director, Analytics R&D, IoT: The pattern of training in the Cloud, with your choices of framework and inferencing at the Edge with a target environment, are especially common in Internet of Things (IoT). In IoT, there is a proliferation of hardware environments on the Edge.
My coworker recently shared this post in Grown and Flown from a mother of a teen who lives with both depression and ADHD. This is a timely share as we approach May which is Mental Health Awareness Month. I’d encourage you to read to better understand this experience or, perhaps,
Everybody likes to learn a bit of interesting trivia... It could make you look smart, or might help you win a bet in a bar. Or maybe give you something to amaze your kids with. Do you know what's the biggest non-domesticated land animal in your state? How about all
SAS/IML programmers often create and call user-defined modules. Recall that a module is a user-defined subroutine or function. A function returns a value; a subroutine can change one or more of its input arguments. I have written a complete guide to understanding SAS/IML modules, which contains many tips for working
You've probably heard by now the new SAS Viya runs on containers orchestrated by Kubernetes. There is a lot to know and learn for both experienced users and k8s noobies alike. I would recommend searching the SAS Communities Library for a wealth of information on deployment, administration, usability, and more.
Government procurement teams are responsible for managing billions of pounds of public expenditure, and taxpayers want more transparency on how their money is being spent. However, experts estimate that procurement errors, waste and abuse can cost central government up to 4.7% of procurement spend.[1] And when government procurement fraud scandals hit
Our world has changed tremendously over the last seventy plus years with more toxins in our environment that I care to speak about. When I sat down to write this article, I was perplexed in where to begin. There are so many environmentally unfriendly exposures that many of us may
Analyzing climate change business risk helps companies choose the most effective actions.
Ranking is a fundamental concept in statistics. Ranks of univariate data are used by statisticians to estimate statistics such as percentiles (quantiles) and empirical distributions. A more advanced use is to compute various rank-based measures of correlation or association between pairs of variables. For example, ranks are used to compute
A few months ago, I published an article about network optimization and how to find an optimal tour when visiting multiple places of interest by using different types of transportation, like buses, trains, tram, metro, and even walking. For a real-world case, I decided to run these optimal tours in
Have you ever brought home a piece of furniture-in-a-box, and felt undue stress while trying to make sense of the directions to assemble it? ... Apparently you're not alone! A recent analysis studied ~50,000 tweets about IKEA furniture, and determined whether the people posting the tweets were frustrated. They then
This blog demonstrates how to create a report that provides only the column headings for data that is missing. The blog also explains how to create, select, and exclude output objects as well as how to generate reports with the SAS® Output Delivery System (ODS). These concepts are relevant to the task of generating a report with the column headings for a data set that contains no (0) observations.
SAS Global Forum 2021 will be jam-packed with inspiring content. Register today to ensure you don't miss a second of this year's event.
