Here's a fun problem to think about: Suppose that you have two different valid ways to test a statistical hypothesis. For a given sample, will both tests reject or fail to reject the hypothesis? Or might one test reject it whereas the other does not? The answer is that two
I use macros extensively in my SAS programs, and over the years have accumulated a few that I find quite useful. The integration of GIT and SAS Studio has made it easy to build a re-usable macro library, so I've put some of the more polished macros I've written in
At SAS, curiosity is at the heart of everything we do. It’s no surprise, then, that it’s one of our core values! Last year, we shared 4 fun facts about the #saslife to rave reviews. So this year, we thought it would be fun to share a few more! In
Several probability distributions model the outcomes of various trials when the probabilities of certain events are given. For some distributions, the definitions make sense even when a probability is 0. For other distributions, the definitions do not make sense unless all probabilities are strictly positive. This article examines how zero
From COVID-19 vaccines, climate change, supply chain issues and everything in between, 2021 set forth a wealth of thought-provoking ideas and data-related topics for us to share with you on this blog. Last year, SAS announced more groundbreaking partnerships and expanded upon its corporate responsibility efforts to help solve some
Leonid Batkhan describes and discusses pros and cons of 3 different algorithms and SAS code implementations to calculate length of overlap of date/time intervals and integer intervals in general.
Heartburn is the most common gastrointestinal symptom affecting more than ⅔ of the US population, but we’ve all likely had heartburn at some point. Proton Pump Inhibitors (PPI’s), drugs typically prescribed for heartburn symptoms (they reduce the acid production in your stomach), are among the top 10 most prescribed medications.
Some colors have names, such as "Red," "Magenta," and "Dark Olive Green." But the most common way to specify a color is to use a hexadecimal value such as CX556B2F. It is not obvious that "Dark Olive Green" and CX556B2F represent the same color, but they do! I like to
There are many ways a therapist can be a resource regarding the topic of separation or divorce. One option is Discernment Counseling. In this blog post, two Triangle-area therapists answer common questions to provide a better understanding of what Discernment Counseling is and is not. Thanks to contributors Erica Blystone,
Last year, I wrote a blog demonstrating how to use the %Auto_Outliers macro to automatically identify possible data errors. This blog demonstrates a different approach—one that is useful for variables for which you can identify reasonable ranges of values for each variable. For example, you would not expect resting heart
Kayla was ready for a change. “I moved from Cary to Ohio to be near family right before the pandemic, and soon after, my manager left SAS for a new opportunity,” she explains. “The effects of 2020 were setting in. I love recruiting in a high-growth environment, and with 2020
Mergers and acquisitions are difficult to pull off, but they can impress when the right strategy is applied. And analyzing your data almost always helps with the right strategy. In the first eight months of 2021, publicly announced M&A activities were valued at more than $3.6 trillion globally and $1.8
The past 20 months of disruptions caused by COVID-19 have been a wake-up call for retailers and consumer goods companies. Unpredictable market trends have caused havoc with categories, brands and products making it harder to predict supply requirements. All of these changes have given rise to the need for consumption
On this blog, I write about a diverse set of topics that are relevant to statistical programming and data visualization. In a previous article, I presented some of the most popular blog posts from 2021. The most popular articles often deal with elementary or familiar topics that are useful to
Read this bulletin for the SAS response to CVE-2021-44228, the Apache Log4j vulnerability.
Welcome to the sixth installment in my series Getting Started with Python Integration to SAS Viya. In previous posts, I discussed how to connect to the CAS server, how to execute CAS actions, and how to work with the results. Now it's time to generate simple descriptive statistics of a CAS table. Let's begin
This article was co-written by Nick Johnson, Product Marketing Manager, Microsoft Partnership. Check out his blog profile for more information. As employees continue to adapt to the reality of remote work — collaborating with teams near and far — it is vital that organizations have the right collaboration and productivity
In a hackathon, teams of participants collaborate and compete to find the best solutions to a business or humanitarian challenge using technology. But unlike many traditional hackathons where participants meet in person for a couple of days, the SAS Hackathon is all-digital and lasts for a month. Prior to the
You can use the Cholesky decomposition of a covariance matrix to simulate data from a correlated multivariate normal distribution. This method is encapsulated in the RANDNORMAL function in SAS/IML software, but you can also perform the computations manually by calling the ROOT function to get the Cholesky root and then
Last year, I wrote almost 100 posts for The DO Loop blog. My most popular articles were about data visualization, statistics and data analysis, and simulation and bootstrapping. If you missed any of these gems when they were first published, here are some of the most popular articles from 2021:
Let's take a look at the design and implementation of SAS functions in financial calculations. We'll do this through examples calculating and analyzing the monthly payment, interest, and principal for CPM/CAM mortgages.
As we wrap up an outstanding year at the RFC, we want to take a moment to celebrate a year of innovation and creativity and thank YOU for joining us to take care of your health and wellness and have LOTS of FUN along the way. Here’s just a few
It feels like yesterday that we were signing a contract with a new vendor, Acclaim, to provide digital badging services for our SAS Certification candidates. That was over five years ago. Since then, Acclaim joined forces with another market leader and became part of Credly. SAS has expanded our badging
SAS' Kelly Fellingham, an advanced analytics software developer, reveals how SAS software's new SASEBEA interface helps you identify patterns in US economics data.
It is increasingly possible to use text analytics to explore different types of data. When a news story this summer caught my eye, I decided to see if I could use SAS Visual Text Analytics (VTA) and SAS Visual Analytics (VA) on customer complaints to provide information that might be
This is a post from a few years back, pre-COVID. It seems particularly timely as many of us may now be planning a visit to see older adults in our family that we have been separated from due to the pandemic. As the holidays approach, one of the highlights
The relationship between insurance companies and their clients has always been tricky due to several factors. But just like any other sector today, insurance organizations are transforming with digital technologies – and these solutions are customer-centric. What’s in store for customer relationships in the insurance industry? Keep on reading to
Introduction In an era of high connectivity and instant gratification, the expectations of customer experience have never been higher. Customers do not simply want but rather expect accessible and responsive communication across a variety of channels. And for organisations, the risks have never been higher. Disgruntled users now have the
We are getting used to seeing banks considering climate risk. After all, it is closely related to other types of risks that financial institutions mitigate and manage. There are two main types of risks associated with climate: Physical risk of financial losses directly related to climate change-related extreme weather events. Transition
Because it is near the end of the year, I thought a blog about "Summarizing" data might be in order. For these examples, I am going to use a simulated data set called Drug_Study, containing some categorical and numerical variables. For those interested readers, the SAS code that I used
