Sometimes, your first impulse may not be correct, like trading in your practical sedan for a hot 2-seater. Other times, your first impulse is perfect, as in the examples below. Suppose the automobile data you wish to analyze resides in a CSV file. Naturally, your first impulse is to import
Like many other computer packages, SAS can produce a contour plot that shows the level sets of a function of two variables. For example, I've previously written blogs that use contour plots to visualize the bivariate normal density function and to visualize the cumulative normal distribution function. However, sometimes you
Recently, SAS released SAS Solutions OnDemand for academics. An academic user who is signed up for this can use the SAS Web Editor application to do all their data analysis over the web using a hosted server at SAS. This frees up the user from having to install the software on their own computers,
A couple of years ago I shared a method for copying any file within a SAS program. It was a simple approach, copying the file byte-by-byte from one fileref (SAS file reference) to another. My colleague Bruno Müller, a SAS trainer in Switzerland, has since provided a much more robust
There's an old expression "easy as pie." Have you ever tried to bake a pie??? ... It's not so easy, LOL! And neither is using pie charts correctly! :) Below are several examples of different kinds of pie charts you can create with SAS/GRAPH. And at the bottom of this
SAS 9 has supported calling R from the SAS/IML language since 2009. The interface to R is part of the SAS/IML language. However, there have been so many versions of SAS and R since 2009, that it is hard to remember which SAS release supports which versions of R. The
This week I read an interesting blog post that led to a discussion about specifying the frequencies of observations in a regression model. In SAS software, many of the analysis procedures contain a FREQ statement for specifying frequencies and a WEIGHT statement for specifying weights in a weighted regression. Theis
Like many of you teachers out there, I spent a lot of time recently preparing for the new school year. At home, it began with the therapeutic organization of children's rooms. As I sat amid in outgrown clothes, last year’s school work, and books to donate, I braced myself and
One of our readers asked if we could explain some of the thinking behind SAS’ recent decision to modify its support for US regional users groups. Over the past five to ten years, users have been telling SAS they need more targeted, more local and more immediate types of support, especially technical
SAS Data Management is a popular topic here on the SAS interwebs. You can find all types of information ranging from thought leadership to white papers to product details. At SAS Global Forum I sat down with Nancy Rausch, one of the principal R&D managers behind the SAS Data Management
Do you know how to create a bar chart using SAS, and when to use what kind of bar chart?!? If the answer doesn't come to you "easy as pie" then this blog is for you! Below are several examples of different kinds of bar charts you can create with SAS/GRAPH.
Please register and join SAS Product Manager Amy Peters on September 26 at 1:00 pm ET for a SAS Talks webinar: SAS 9.4: What's New for SAS Administrators. This SAS Talks webinar is laser-focused on enhancements and changes that will interest SAS administrators. Specifically, Amy will highlight how the new
Another summer has almost come and gone and fall is on its way bringing cooler temperatures, lower humidity, and colorful leaves. However, just because fall is knocking on our door doesn’t mean we have to stop enjoying our favorite summer produce. If you’re a home gardener or a frequent flyer
In a previous post, I showed how to solve differential equations in SAS by using the ODE subroutine in the SAS/IML language, which solves initial value problems. This article describes how to draw phase portraits for two classic differential equations: the equations of motion for the simple harmonic oscillator and
If you're a student or young professional, you're in luck! I've compiled a cheat-sheet of the grants, scholarships and mentorship programs offered at SAS Users Group conferences. Why attend a conference in the first place? Simple. You can increase your SAS knowledge, network with experienced SAS professionals and generally improve
Differential equations arise in the modeling of many physical processes, including mechanical and chemical systems. You can solve systems of first-order ordinary differential equations (ODEs) by using the ODE subroutine in the SAS/IML language, which solves initial value problems. This article uses the equations of motion for the classic simple
Creating bar charts with group classification is very easy using the SG procedures. When using a group variable, the group values for each category are stacked by default. Using the sashelp.prdsale data set and default STAT of SUM, here is the graph and the code. SGPLOT code: proc sgplot data=sashelp.prdsale;
It's been almost 5 years since I posted one of the first custom tasks for SAS Enterprise Guide. It was a task that made it easier to convert SPSS data files into SAS data sets. Like many projects that begin as custom tasks, this one later became a feature in
Last week I presented two talks at the University of Wisconsin at Milwaukee, which has established a new Graduate Certificate in Applied Data Analysis Using SAS. While in Milwaukee, I ran into an old friend: the ODS LISTING destination. One of my presentations was a hands-on workshop titled Getting Started
Some handy folks at SAS got together and created a series of videos to help you get started with the SAS 9.4 installation. It starts with the basics that explain what you should do with your Software Order Email. Step two provides videos for creating or moving the software depot.
I am passionate about teaching. My colleagues would probably say this is the understatement of the year. And it likely has something to do with the fact that both of my parents were teachers. I started my teaching career at the university level and after many years an unexpected opportunity
SASuser power! Does this phrase conjure up any images for you? I visualize SAS users across the globe, addressing messy data, combating fraud, and making use of business analytics to provide insight and add business value for organizations around the world. We, SASusers are powerful! With the Potential of One
Sometimes it is useful in the SAS/IML language to convert a character string into a vector of one-character values. For example, you might want to count the frequency distribution of characters, which is easy when each character is an element of a vector. The question of how to convert a
This week's SAS tip is from Kevin D. Smith and his new book PROC TEMPLATE Made Easy: A Guide for SAS Users. Kevin is a software developer at SAS with extensive experience supporting PROC TEMPLATE and underlying ODS technologies. We're excited that Kevin decided to write his book and hope
Fall is rolling around, which means time to plan and attend at least SAS regional conferences. I’m heading to the Southeastern SAS User’s Group (SESUG) conference in beautiful St. Petersburg, Florida. While I do love the conference, they had me at St. Pete Beach!
Do you know (right off the top of your head) the simple SAS/GRAPH code you would use to create line graphs? ... If not, then this tutorial is for you! A line plot is basically a scatter plot where the markers are connected. A line plot should only be used
With the popularity of SAS Grid Manager, this question often comes up: which clustered or shared file system should we use with the multiple nodes of the SAS Grid? This is a question that needs to be thought through very carefully because the amount of time and effort to fix
Ways We Excrete Toxins You learned in the previous Chews Strategically post, Foods for Natural Detox, that certain foods provide important nutrients that assist the liver in transforming toxins so they can be excreted from the body. After the toxins are transformed into water soluble substances they are excreted through
Finding the maximum value of a function is an important task in statistics. There are three approaches to finding a maxima: When the function is available as an analytic expression, you can use an optimization algorithm to find the maxima. For example, in the SAS/IML language, you can use any
Scatter plots are probably the simplest kind of graph, and provide a great way to visually look for relationships between two variables. But, do you know (right off the top of your head) the simple SAS/GRAPH code you would use to create them? ... This tutorial leads you step-by-step through the
