This blog post highlights more SAS Global Forum papers chosen by SAS Press authors.
How to count words in SAS with the COUNT functions, and concatenate strings by using the CAT functions. Use these tips to modernize your SAS code!
Three bestselling SAS Press authors feature their favorite papers from SAS Global Forum 2018.
A SAS programmer recently asked how to interpret the "standardized regression coefficients" as computed by the STB option on the MODEL statement in PROC REG and other SAS regression procedures. The SAS documentation for the STB option states, "a standardized regression coefficient is computed by dividing a parameter estimate by
Did you know that the call for content is now open for SAS Global Forum 2019? Get the details and see why next year's Conference Chair MaryAnne DePesquo is excited about the big event in Dallas, Texas, April 28-May 1, 2019.
Visualization of data density estimation, which is often used in statistical analysis and machine learning, will show the data’s characteristics like distribution, skewness and modality, etc. Commonly-used data density visualizations include boxplot, histogram, kernel density estimates, and some other plots. This blog post visualizes the kernel density estimates superimposing on histogram using SAS Visual Analytics.
When I'm at a social gathering, someone always asks what type of work I do. I like to keep my social life separate from my work, therefore I usually give a vague answer such as "software" (and quickly change the topic). How vague or specific is your response? How vague
This article shows how to perform an optimization in SAS when the parameters are restricted by nonlinear constraints. In particular, it solves an optimization problem where the parameters are constrained to lie in the annular region between two circles. The end of the article shows the path of partial solutions
그래프를 만들 때 가장 어려운 작업은 무엇일까요? 바로 데이터를 준비하는 것인데요. 오늘은 엑셀 데이터를 SAS로 가져오고, 전치하고, 첫 열의 값을 데이터 값으로 사용하고, 플롯으로 요약하는 방법을 차례대로 소개해드리고자 합니다. 오늘 예시에서는 학생 대출 채무에 관한 데이터가 사용되는데요. 몇 년 전, 학생 대출 채무가 급증하면서 큰 이슈가 됐었고, 아래는 관련 기사에서 쓰인
Even though I’ve worked at SAS for nearly 30 years, I still get excited when great things come together for our customers! This year we are hosting the very first hackathon at our Analytics Experience conference in San Diego - the AnalyticsX Hackathon. Analytics Experience is in its third year
Elections are in the news again, therefore I have been on the lookout for interesting graphs. I recently found some graphs of the Census Current Population Survey (CPS) Voting and Registration Supplement data, and tried to improve them. Follow along if you're interested in voter data, or creating better graphs!
Hash tables are a very powerful and flexible data structure. Most SAS applications of hash tables focus on just one of their many powerful facilities: table lookup. Hash tables are a fantastic table lookup tool and their use for that should never be diminished. However, hash tables can do so
I peruse many different websites to get my news, and I always keep an eye out for good (or bad) presentations of data. I recently saw a posting on reddit claiming "U.S. GDP is greater than the total of all others combined." This news seemed too good to be true
SAS Viya has opened an entirely new set of capabilities, allowing SAS to analyze on cloud technology in real-time. One of the best new features of SAS Viya is its ability to pair with open source platforms, allowing developers the freedom of language and implementation to integrate with the power
Several weeks ago, I wrote about practical advice from a Chief Data Scientist in my blog “From Aristotle to Pi: Practical advice from a chief data scientist.” Now I want to offer my advice as a newbie trying to navigate through machine learning concepts and how to code them. Over
When you use a regression procedure in SAS that supports variable selection (GLMSELECT or QUANTSELECT), did you know that the procedures automatically produce a macro variable that contains the names of the selected variables? This article provides examples and details. A previous article provides an overview of the 'SELECT' procedures
A programmer recently asked a question on a SAS discussion forum about design matrices for categorical variables. He had generated a design matrix by using PROC GLMMOD and wanted to use the design columns in a subsequent procedure. However, the columns were named COL1, COL2, COL3,..., so he couldn't tell
You should play a little. Add dots. Add color. Your PROC REPORT output does not have to be boring. As a matter of fact, it can be both functional and appealing. Any Unicode value will do, but this blog shows how to use the Unicode value for a dot (filled
Getting started with SAS Viya and RStudio -- making the connection, and submitting my first commands via CAS actions.
Since the late 1990s, SAS has supplied macros for basic bootstrap and jackknife analyses. This article provides an example that shows how to use the %BOOT and %BOOTCI macros. The %BOOT macro generates a bootstrap distribution and computes basic statistics about the bootstrap distribution, including estimates of bias, standard error,
"Code golf" is a fun programming pastime that challenges you to solve a problem with the least amount of code possible. Like regular golf, the goal is to use fewest code "strokes" to hit the mark. Here's a recent challenge that was posted to me via Twitter. @cjdinger @SASJedi got
Which character variables have the highest frequency count? You can easily determine this using a variety of procedures that calculate frequency count. For example, the FREQ Procedure or the MEANS Procedure. This blog post illustrates this process through two examples.
SAS batch jobs can generate many log files that accumulate over time. In this post, we present a SAS program that cleans up old log files on your system.
The Base SAS DATA step has been a powerful tool for many years for SAS programmers. But as data sets grow and programmers work with massively parallel processing (MPP) computing environments such as Teradata, Hadoop or the SAS High-Performance Analytics grid, the data step remains stubbornly single-threaded. Welcome DS2 –
Did you know that 80 percent of an analytics life cycle is time spent on data preparation? For many SAS users and administrators, data preparation is what you live and breathe day in and day out. Your analysis is only as good as your data, and that's why we wanted
The Geo Map Visualization has several built-in geographical units, including country and region names and codes, US state names and codes, and US zip codes. You can also define your own geographic units. This paper describes how to identify any geographic point of interest, or collection of points, on a map to create custom maps in SAS.
It seems only a few months back I posted an article on creating Pie Charts using a GTL based macro. Well, looking back, that was almost 6 years ago!! Recently, a colleague here at SAS needed to create Pie Charts in his report along with other plots created using SGPLOT
There are many ways to avoid transcoding problems when you have national language characters in SAS programs that you save from a SAS®9 (English) session and move to a UTF-8 environment. In this article, we'll share tips to help you avoid such issues.
I've said it before: spreadsheets are not databases. However, many of us use spreadsheets as if they were databases, and then we struggle when the spreadsheet layout does not support database-style rigor of predictable rows, columns, and variable types -- the basic elements we need for analytics and reporting. If
When making a new piece of code, I like to use the smallest font I can read. This lets me fit more text on the screen at once. When presenting code to others, especially in a classroom setting, I like to make the font large enough to see from the back of the room. Here’s how I change font size in SAS in our three programming interfaces.
