Last year, a user asked about creating a "Turnip Plot" as used in this study of Caesarian Section Rates. Primarily, this is similar to a histogram on the y-axis for each unique value on the y-axis. A marker is drawn for each occurrence, starting from the center. Back then, I
A common question on discussion forums is how to compute a principal component regression in SAS. One reason people give for wanting to run a principal component regression is that the explanatory variables in the model are highly correlated which each other, a condition known as multicollinearity. Although principal component
The previous post on Multiple Blank Categories showed how to include multiple blank categories on the axis. But, given the purpose for this was to separate different segments in the data, I also included ideas on how to segmented a discrete axis using reference lines or Block Plot. A similar idea
To make accurate predictions, it is necessary that the sample data you use for model development is compatible with the target population. The distribution of each input used in the model should be similar in the sample and the target population. In your model you should include only those variables
There are many compelling reasons existing SAS users might want to start integrating SAS Viya into their SAS9 programs and applications. For me, it comes down to ease-of-use, speed, and faster time-to-value. With the ability to traverse the (necessarily iterative) analytics lifecycle faster than before, we are now able to generate
Reading an external file that contains delimiters (commas, tabs, or other characters such as a pipe character or an exclamation point) is easy when you use the IMPORT procedure. It's easy in that variable names are on row 1, the data starts on row 2, and the first 20 rows
“The difference between style and fashion is quality.” -Giorgio Armani With an out-of-the-box SAS Enterprise Guide (EG) installation, when you build a report in SAS EG it is displayed in a nice-looking default style. If you like it, you can keep it, and continue reading. If you don’t quite
I hope everyone has noticed some new shortcuts in Graphically Speaking. As you scroll down and look to the right, there are shortcuts for Sanjay's getting started and clinical graphs posts and one for my advanced blogs. When Sanjay asked me to make an icon for my advanced blogs, at
The goal of this article is to describe the steps needed to configure the bridge that allows SAS Data Integration 4.902, based on SAS 9.4M4, to load data directly into CAS on SAS Viya 3.2. Of course, SAS 9.4M5 simplifies this process, as a SAS/CONNECT communication will no longer be required, enabled
My father introduced me to Gene Kelly and Donald O’Connor when I was 10… in a figurative sense. Dad loved musicals and Singin’ In The Rain became one of my favorites. I was obsessed with their tap dance to Moses Supposes and practiced every day after school until I ‘got
To get full value from analytics programs, Todd Wright says be sure you can first access, integrate, cleanse and govern your data.
In a previous article, I discussed the lines plot for multiple comparisons of means. Another graph that is frequently used for multiple comparisons is the diffogram, which indicates whether the pairwise differences between means of groups are statistically significant. This article discusses how to interpret a diffogram. Two related plots

In growing areas such as the Research Triangle Park, there is always the tough decision between developing land for business, or keeping it natural for parks and recreation. SAS is fortunate to have the great hiking trails at Umstead Park just across the road to the north - it's the
In the field of machine learning, online learning refers to the collection of machine learning methods that learn from a sequence of data provided over time. In online learning, models update continuously as each data point arrives. You often hear online learning described as analyzing “data in motion,” because it
You know the value of your SAS Certification; does the rest of the world? A recent MONEY and Payscale.com study named SAS Analytics skills as the most valuable skills to have in today’s job market and certification is the best way to demonstrate those skills. Recognition like this helps solidify
If you checked the Work/Life calendar of events this summer, you may have seen ads to meet with me to discuss character strengths and how to incorporate them into your everyday. It’s been a pretty popular offering, and that’s really no surprise. Who doesn’t want to learn more about themselves
My sons were amazing sleepers...as babies. Around age 2.5, mutiny ensued. My eldest endured the wild combination of potty training, a new baby brother, transitioning into a "big boy" bed, and a beautiful developing imagination. While the youngest didn’t have the new baby to taunt his sleep, he did get
In a SAS Viya 3.2 environment two types of content can be created: SAS Visual Analytics Reports and Data Plans. For administrators, who may want to manage that content within a folder structure, there are some things to keep in mind. In the current release, both types of content can be
Off and on, users have expressed the need to include multiple blank categories on a discrete axis. Often, this is desirable to separate groups of bars (or categories) in a graph due to some difference their definition. Such a case was discussed in this blog article on using non breaking
Would you like to format your macro variables? Easy! Just use the %FORMAT function, like this: What?! You never heard of the %FORMAT function? Of course not, cuz it doesn't exist! No problem. Just create it, like this: %macro format(value,format); %if %datatyp(&value)=CHAR %then %sysfunc(putc(&value,&format)); %else %left(%qsysfunc(putn(&value,&format))); %mend format; The %FORMAT
Phil Simon chimes in on the tendency to rely upon these tools too much.
SAS will be represented by more than 20 attendees at the INFORMS Annual Meeting at the George R. Brown Convention Center (GBCC) in Houston, Texas. Officially the conference runs from Sunday, Oct. 22 through Wednesday, Oct. 25, but our activities in Houston start even earlier. Technology Workshops on Saturday, October
Last week Warren Kuhfeld wrote about a graph called the "lines plot" that is produced by SAS/STAT procedures in SAS 9.4M5. (Notice that the "lines plot" has an 's'; it is not a line plot!) The lines plot is produced as part of an analysis that performs multiple comparisons of
ODS Graphics procedures primarily strive towards the following goal: "Make simple graphs easy and complex graphs possible". SGPLOT procedure allows you create simple graphs with a single plot statement, and create complex graphs by layering together or combining multiple plot statements. Generally, the appearance follows the guidelines set by industry
Every year in early October, the eyes of the world turn to Sweden and Norway, where the Nobel Prize winners are announced to the world. The Nobel Prize is considered the world's most prestigious award. Since 1901, the Prize has been presented to individuals and organizations that have made significant
In this education analytics series of blog posts, we have been on a journey to learn how education customers are turning their data into insights to be a more data-informed and analytical organization. So far on our journey, we learned how education customers are using SAS, the positive impact that SAS
Axis tables can use the SUM= option to summarize data and display means, medians, sums, and percentages. They can instead be used to display data, text, and statistics without any summarization.
I’ve been making note of recent interactions and observations with different companies that I’ve done business with lately. My goal is to share with you real ways in which excellent customer experiences are shaped. Observation #1: Witty conversations rule As I write this, I’m sitting at a Panera Bread restaurant
As analytics advances into more areas of our everyday life there is an increased need to understand just what it is that analytics is accomplishing for us. I find there is a quicker acceptance of an analytical solution and even excitement if there is a good conceptual understanding of what
