SAS Help Center: Your gateway to documentation
To improve is to change; to be perfect is to change often.-Winston Churchill If you've visited SAS documentation (also known as the "SAS Help Center") lately, you may have noticed that we've made some fairly significant changes in the documentation for SAS products and solutions. The new site is organized in a new way, search
Finding your Dream Car with a little macro magic
Suppose you want a list of car manufacturers from the CARS dataset. Easy! Call the %CHARLIST macro from a %PUT statement, like this: The CHARLIST macro generates a list of unique values of a selected variable from a selected dataset. So does PROC FREQ. But, if you don't need statistics, the CHARLIST
Eat Candy as One of Your Vegetables
The North Georgia Candy Roaster I’m a North Carolina native, born and raised. So, it was quite a surprise at a recent trip to the farmers market when I came across this odd looking, large pink banana-shaped pumpkin-squash that I had never laid eyes on. When I asked what it
Advanced ODS Graphics: Curve labels and date axes
Curve labels in series plots can be positioned inside or outside the graph. Date variables can be specified as TYPE=LINEAR with a date format or more commonly as TYPE=DATE. Sometimes external curve labels might appear below or above the graph, particularly with TYPE=DATE axes. This post shows you ways to move them to the right of the graph.
Should you use principal component regression?
This article describes the advantages and disadvantages of principal component regression (PCR). This article also presents alternative techniques to PCR. In a previous article, I showed how to compute a principal component regression in SAS. Recall that principal component regression is a technique for handling near collinearities among the regression
Do you say coke, pop, or soda?
Quick Quiz! Where might you hear the following conversation? ... Waitress: "What would you like to drink, honey?" Customer: "I'll have a coke." Waitress: "What kind?" Customer: "Diet Pepsi."

Turnip plot redux
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
Principal component regression in SAS
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
Tips and tricks: Segmented discrete axis
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
Compatibility between model data and the target population
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
Top 12 Advantages of SAS Viya
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
Tips for using the IMPORT procedure to read files that contain delimiters
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 most-asked math question: When will I ever use this?
What a powerful question! And it's one commonly posed to math teachers all over the world. Need help with an answer? Here are a few to consider. Suppose you're asked the question about a piecewise function. Let's start with the standard definition: "a combination of two or more functions, each represented
SAS Viya 3.2 Bridge for SAS Data Integration Studio 4.902 (on SAS 9.4M4) configuration steps
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
Dance is Joy
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

The diffogram and other graphs for multiple comparisons of means
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

Exercising your way through a sleep deprived day
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
