The number of possible bootstrap samples for a sample of size N is big. Really big. Recall that the bootstrap method is a powerful way to analyze the variation in a statistic. To implement the standard bootstrap method, you generate B random bootstrap samples. A bootstrap sample is a sample
Many cities have Open Data pages. But once you download the data, what can you do with it? This is my fifth in a series of blog posts where I download public data about Cary, NC, and demonstrate how you might analyze that type of data (for Cary, or any
You can use the bootstrap method to estimate confidence intervals. Unlike formulas, which assume that the data are drawn from a specified distribution (usually the normal distribution), the bootstrap method does not assume a distribution for the data. There are many articles about how to use SAS to bootstrap statistics
Welcome back to my SAS Users blog series CAS Action! - a series on fundamentals. I've broken the series into logical, consumable parts. If you'd like to start by learning a little more about what CAS Actions are, please see CAS Actions and Action Sets - a brief intro. Or
There is general agreement that artificial intelligence (AI) has the potential to transform health care. However, there is also little doubt that this process has not yet really started. Hospitals and health care providers have been relatively slow to adopt AI solutions on a large scale. Beyond automation There are
This post, written by Radhikha Myeni and Jagruti Kanjia, will demonstrate how easy it is to build and deploy a machine learning pipeline by using SAS and Python. The Model Studio platform provides a quick and collaborative way to build complex pipelines by dragging and dropping nodes from a web-based
One of the most common reasons for discontinuing breastfeeding is low milk supply – real or perceived. Dwindling breast milk supply can be caused by a variety of factors including ineffective latch, not nursing often enough, hormones, certain medications, stress and nutrition. The good news is many supply issues can
For graphing multivariate data, it is important to be able to convert the data between "wide form" (a separate column for each variable) and "long form" (which contains an indicator variable that assigns a group to each observation). If the data are numeric, the wide data can be represented as
During lockdowns across Europe and beyond, we all moved our lives online. We worked remotely and had meetings via Teams or Zoom. We also socialised and shopped online. For many people, this was familiar territory. For others, it opened up a whole new world—and highlighted significant problems with the ‘old
Curious about how the COVID-19 vaccine has impacted the world around you? This SAS Viya powered data visualization shows information related to the COVID-19 vaccination efforts in the United States. Here's what you can learn from this dashboard. Percentage of vaccinated Americans In August 2021, the CDC reported that over 50% of
Editor's note: Jack Liu is a member of SAS Analytics Explorers, a SAS community that is dedicated to exploring analytics, sharing knowledge, having fun and helping SAS users in their careers. Members were recently invited to share their analytics journeys, and Jack responded with his impressive story. If you're a
If you’re curious about what it’s like to work at SAS, you’re in the right place. Our people are always asking, “What if?" and pushing the bounds of innovation, and their curiosity is at the core of our company. Today, meet Annette Green, our Regional Vice President of the DACH region in EMEA. She’s sharing about her
Many cities have Open Data pages. But once you download the data, what can you do with it? This is my fourth in a series of blog posts where I download public data about Cary, NC, and demonstrate how you might analyze that type of data (for Cary, or any
"Protect breastfeeding: a shared responsibility" is this year's theme for World Breastfeeding Week. SAS has been a strong supporter of mothers who desire to breastfeed their babies by making offices adaptable to pumping/nursing and providing comfortable Mother-at-Work pump rooms across campus. The on-site Health Care Center has prioritized supporting breastfeeding mothers and infants for nearly
In our previous section of the series we discussed the impact of missingness and techniques to address this. In this final section of the series we look at how we can use drag-and-drop tools to accelerate our EDA. As mentioned at the beginning of this series, SAS Viya offers multiple
SAS' Leonid Batkhan shows you how to remove ANY leading characters (not just blanks) from text strings to tidy up your data.
This article shows how to create a "sliced survival plot" for proportional-hazards models that are created by using PROC PHREG in SAS. Graphing the result of a statistical regression model is a valuable way to communicate the predictions of the model. Many SAS procedures use ODS graphics to produce graphs
Reasoning frameworks of artificial intelligence used in criminal justice and health care systems move us to rethink how AI can be constructed to help foster an equitable society. We interact daily with algorithms that over time predict and inform our actions. Spam filters in e-mail and real-time mapping technologies on
SAS and Microsoft are working tirelessly to improve offerings and connectivity between SAS Viya and Microsoft Azure environments across industries.
I’ve worked with expectant moms for a quarter century. I can spot a new mom-to-be from a mile away. There is a lot of wonderment with new mommies. They have lots of questions and are unsure if they are doing everything right, fear what they identify as shortcomings and put
Many cities have Open Data pages. But once you download the data, what can you do with it? This is my third in a series of blog posts where I download several datasets from Cary, NC's open data page, and give you a few ideas to get you started on
In Part 1 of my series fetch CAS, fetch!, I executed the fetch CAS action to return rows from a CAS table. That was great, but what can you do with the results? Maybe you want to create a visualization that includes the top five cars by MSRP for all

On September 2 (3pm UTC / 11am EDT), I'll be joining Jonathon Karelse, CEO of NorthFind Management, for an interactive "fireside chat" on the application of Behavioral Economics in demand planning. This is part of the Foresight Webinar Series, and registration is free. Since we first met at an Institute
The nervous system! What an amazing and complex superhighway within us all! While we may not think of what’s going on underneath the surface, this system delivers information to and throughout the brain and is composed of the brain, brainstem, cranial nerves, spinal nerves, spinal cord and the enteric nerves.
When people think about sports, many things may come to mind: Screaming fans, the intensity of the game and maybe even the food. Data doesn’t usually make the list. But what people may not realize is that data is behind everything people love about sports. It can help determine how
A previous article discusses the geometry of weighted averages and shows how choosing different weights can lead to different rankings of the subjects. As an example, I showed how college programs might rank applicants by using a weighted average of factors such as test scores. "The best" applicant is determined
Fueled by a number of factors, including a global pandemic, data analytics skills are in high-demand. Organizations like the Youth Employment Services (YES) are well aware of the abundance of data and its growing complexity. That's why they partnered with SAS last year to provide free learning pathways to help
Many cities have Open Data pages. But once you download the data, what can you do with it? This is my second blog post where I download several datasets from Cary, NC's open data page, and and give you a few ideas to get you started on your own data
From this pandemic, every one of us has experienced some kind of loss or something that feels taken away. It could be a person, an activity, an event, an opportunity or even conceptual things like a sense of safety or normalcy. When I worked for hospice, it was routine to
