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.
Interview with Dr. Christian Rammer (ZEW), who leads projects as far as innovation economics and business dynamics at ZEW.
In the second of two posts spotlighting SAS R&D innovators, SAS' Udo Sglavo interviews Chris Barefoot, Matthew Galati, Courtney Ambrozic and Davood Hajinezhad.
Curiosity is at the heart of everything we do here at SAS. It’s how we got our start, and it’s what will continue to drive us forward. Our people take pride in using their curiosity and creativity to answer all sorts of questions – questions that help customers, communities, and people around the world. Today, hear the unique stories of just a few of
The ranks of a set of data values are used in many nonparametric statistics and statistical tests. When you request a statistic or nonparametric test in SAS, the procedure will automatically compute the ranks that are needed. However, sometimes it is useful to know how to compute the ranks yourself.
Predictive models and medical image analysis have the potential to transform health care delivery. To accelerate innovative approaches in health analytics, teams around the world are participating in a global hackathon. In scientific communities, it's well-known that the fastest way to drive progress and discover new ideas is collaboration with
In the first of two posts spotlighting SAS R&D innovators, SAS' Udo Sglavo introduces you to developers Amy Shi, Maggie Du and Phil Helmkamp.
Minimize processed foods, cook more meals from scratch…we know, we know. But let’s be honest, making the transition away from packaged, processed foods is tough - they’re convenient and comfortable, I get it. However, homemade versions are often cheaper, almost always taste better and really aren’t difficult to make.
SAS' Leonid Batkhan explores shell scripting as an alternative way to implement parallel processing.
It can be frustrating to receive an error message from statistical software. In the early days of the SAS statistical graphics (SG) procedures, an error message that I dreaded was ERROR: Attempting to overlay incompatible plot or chart types. This error message appears when you attempt to use PROC SGPLOT
A solid business strategy addresses insurance accounting standards and much more.
Following is Editor Len Tashman's preview of the new issue of Foresight: The International Journal of Applied Forecasting. Jonathon Karelse, author of the lead story, will be presenting in the Practitioner Track of the International Symposium on Forecasting (June 27-30). Preview of Foresight #61 (2021:Q2) For many years, we’ve identified
Digital channels open the door to synthetic identity fraud. Luckily, artificial (AI, that is) can defeat synthetic.
Most introductory statistics courses introduce the bar chart as a way to visualize the frequency (counts) for a categorical variable. A vertical bar chart places the categories along the horizontal (X) axis and shows the counts (or percentages) on the vertical (Y) axis. The vertical bar chart is a precursor
With unemployment at a three-year high, the socio-economic impact of the COVID-19 pandemic has hit the UK hard. While significant progress has now been made on the clinical side of the crisis, and the success of the vaccination programme is a cause for optimism, the impact on the economy will
This is another in my series of blog posts where I take a deep dive into converting R graphs into SAS graphs. Today we'll be working on pie charts. I know, I know ... you visualization 'purists' might be wagging your finger at me, and saying "pie charts are no good."
As mentioned in my article about Monte Carlo estimate of (one-dimensional) integrals, one of the advantages of Monte Carlo integration is that you can perform multivariate integrals on complicated regions. This article demonstrates how to use SAS to obtain a Monte Carlo estimate of a double integral over rectangular and
A previous article shows how to use Monte Carlo simulation to estimate a one-dimensional integral on a finite interval. A larger random sample will (on average) result in an estimate that is closer to the true value of the integral than a smaller sample. This article shows how you can
If I were to say that we live in uncertain times, that would probably be an understatement. Therefore, I won’t say that. Oops, I already did. Or did I? For centuries, people around the world have been busy scratching their heads in search of a meaningful answer to Shakespeare’s profoundly
The time for experimenting with artificial intelligence (AI) is over. In a COVID-19 climate, it is important to be able to quickly scale up analytical models to industrial processes. SAS believes the solution can be found in democratizing AI. Most manufacturing businesses have large amounts of data at their disposal.
