If you perform a weighted statistical analysis, it can be useful to produce a statistical graph that also incorporates the weights. This article shows how to construct and interpret a weighted histogram in SAS. How to construct a weighted histogram Before constructing a weighted histogram, let's review the construction of
‘Quality‘ means many things to many people. It’s subjective and depends on the industry and product being made, but the fundamental objective is to provide the best product to the right standard associated to fit, form and function. And cost and required profit margin must also be taken into account.
"Coming to America" - it's been the name of a funny movie and a dramatic song (can you name the actor & singer without cheating?!?) It's also been a dream for many, and an action for some. People have been coming to America both legally and illegally for many years, but there's one special category
As smart city endeavors continue to ramp up globally, city planners and leaders are often curious to learn how cities around the world are planning to make their cities smarter with the Internet of Things. Recently, my colleagues and I met with a team from a major city in China
To do their jobs well, Joyce Norris-Montanari says users doing analytical data preparation need access to both standardized and raw data.
How can you specify weights for a statistical analysis? Hmmm, that's a "weighty" question! Many people on discussion forums ask "What is a weight variable?" and "How do you choose a weight for each observation?" This article gives a brief overview of weight variables in statistics and includes examples of
On a recent visit to an In-House Users Group meeting at a Pharmaceutical company, I presented a 1/2 day seminar on creating Clinical Graphs using SG Procedures. Polling the audience for their experience with these procedures indicated that many SAS users are not familiar with these new ways to create graphs. So,
For our third installment in this blog post series, let’s continue our journey to learn more from three SAS education customers. Today, we'll hear about the benefits their users and institutions have received by using SAS for data visualization and analytics. In this post, you'll hear from: Linda Sullivan, Assistant Vice President
This post shows how to use PROC SGPLOT together with PROC TRANSREG to fit monotonically increasing or decreasing functions through a scatter plot.
I recently paddled in a boat race, and was wondering how I did compared to all the other paddlers. And being a Graph Guy, I decided I should find a cool way to graph the data ... Here's some background information ... There's a great organization called Bridge II Sports
One of the best parts of my job is hearing about all the cool ways people are using data for good. Increasingly, many of these stories are related to the Internet of Things, including: Smart pills that help patients stick to their treatment regimens. These ingestible sensors can monitor patients’
If you’re in the field of analytics, you’ve undoubtedly heard about SAS Viya. Designed for all analytic professionals, regardless of skills or experience, SAS Viya seamlessly handles big, complex, diverse data. It also supports any programming language, allowing analysts to choose the tool that makes them most productive. Recently a colleague
In the previous article on Getting Started with Vertical HighLow Plot, I described how we can use the HighLow plot to display the stock price by date. The HighLow plot is specifically designed for such use cases as shown below. The data is downloaded from the Nasdaq web site, and
Depending on who you speak with you will get varying definitions and opinions regarding demand sensing and shaping from sensing short-range replenishment based on sales orders to manual blending of point-of-sales (POS) data and shipments. Most companies think that they are sensing demand when in fact they are
Orbitz recently published a map showing the most popular international travel destination for each of the 50 US states. It was an interesting map ... but of course, me being the Graph Guy, I had to pick it apart and create my own version. Follow along, and explore this interesting
Many of us struggle with getting enough good quality sleep. I have a 9 month old daughter, so I am well aware of the struggles and the consequences of not getting enough sleep. Winding down from the day is one of the top reasons why it takes many of us
Last month I vowed to take time off from watching TV. I worried I was wasting time that could be spent in better ways. I entered that commitment with optimism for what I could achieve during the time off. As it turned out instead, my body was waiting to teach me
Will the IoT live up to the hype? Yes. A most resounding YES. In fact, it will exceed the hype, because we don't even know all the IoT possibilities yet. We don’t know what we don’t know, and that lack of imagination limits even our hype. Where we are with
David Loshin describes how data as a service supports fast deployment, easy accessibility and data reuse.
Recent news reports indicate that the number of illegal immigrants apprehended along the US/Mexican border has dropped significantly since Trump took office. So, even though Trump hasn't had time to build a physical wall, perhaps there's a virtual wall in place now (built from the change in attitudes)? I've seen
This is the first in a series of posts about machine learning concepts, where we'll cover everything from learning styles to new dimensions in machine learning research. What makes machine learning so successful? The answer lies in the core concept of machine learning: a machine can learn from examples and
When an extremely rare aye-aye lemur named Agatha was born undersized at the Duke Lemur Center earlier this year, there was immediate cause for concern. There are only 23 captive aye-ayes in the US, and the wild population is at “very high risk of extinction” according to the International Union for
With the fifth maintenance release of SAS 9.4 (SAS 9.4M5) now available, it seems like a good time to get a refresher on some of the ways you can upgrade your existing SAS deployments to the latest release. Among several benefits, SAS 9.4M5 provides closer integration with the CAS in-memory runtime engine
My article about Fisher's transformation of the Pearson correlation contained a simulation. The simulation uses the RANDNORMAL function in SAS/IML software to simulate multivariate normal data. If you are a SAS programmer who does not have access to SAS/IML software, you can use the SIMNORMAL procedure in SAS/STAT software to
This is the 7th installment of the Getting Started series. The audience is the user who is new to the SG Procedures. Experienced users may also find some useful nuggets of information here. Starting with SAS 9.3 which was released 6 years ago, the SGPLOT procedure supports many new plot types including
Reshma Saujani, of Girls Who Code, doesn’t have the background you’d expect for the person leading an organization whose mission is to inspire, educate and equip young women with computing skills to pursue 21st-century opportunities. She’s not a coder or computer science graduate, and she grew up terrified of math
The second part of this series takes us to Rotterdam, main port of Europe and the residence of Veneficus, a 10-year young and ambitious boutique analytics firm. They have already scored accolades in the Dutch FD Gazellen Award for fast growing companies. In addition, they also won a ‘Best Employer’
You have to be able to trust the data that you are working with, whether it’s data processing or analysis that you are involved with. And there is a strong correlation between that trust and data quality. Is it possible to determine data quality without monitoring mechanisms?
How do the North American amusement parks compare in popularity? If this question was to come up during a lunch discussion, I bet someone would pull out their smartphone and go to Wikipedia for the answer. But is Wikipedia the definitive answer - how can we tell if Wikipedia is wrong?
There is one thing that is consistent during this time of year – planning Breast Cancer Awareness events at SAS and throughout the community. I have a deep passion due to the family history, genetics and simply wanting to help others. I’m also a strong believer in research, education and
