My first thoughts on hearing that we’d be bringing out a new edition of JMP Start Statistics were, “But how do we improve on an already great book? What could be better?” JMP Start Statistics has been such a big success with JMP users for a long time, so the authors
This is a third post on newspaper stories that I recently read. Today's post deals with science, politics, and rising sea levels. Incidentally, the title is a blatant reference to John Allen Paulos's brilliant book, A Mathematician Reads the Newspaper. Senate approves law that challenges sea-level science The NC legislature
This is my second post on some newspaper articles that I recently read. Today's post deals with academic fraud. Questions linger in academic fraud case Over the past year, the News and Observer has occasionally reported on a scandal at the University of North Carolina at Chapel Hill in which
This past weekend was Father's Day, so I took some time to relax and read the newspaper. I found several stories that suggested interesting statistical questions. Unfortunately, the data are not available for analysis. Nevertheless, the stories are worth sharing. Over the next few days, I'll post my thoughts on
Wizard Harry Potter makes magic just waving his wand around and shouting out spells. Using SAS Enterprise Guide (and you are welcome to shout out your own commands too) you can create some magic, allowing the Stored Process Wizard to code for you. On Step 2, the "Include code for"
To celebrate special occasions like Father's Day, I like to relax with a cup of coffee and read the newspaper. When I looked at the weather page, I was astonished by the seeming uniformity of temperatures across the contiguous US. The weather map in my newspaper was almost entirely yellow
A colleague was recently working with a web service that supplies some datetime values using the Microsoft Windows internal representation. He called the web service to retrieve those values (along with other data) from SAS, and he needed convert these values to SAS date-time values. The Microsoft definition for a
When I was growing up, summertime always meant a road trip to see my grandparents and great-grandparents in Concord, California, just outside San Francisco. Most of our time in Concord was spent shuffling between relatives but my parents always made time for a day trip into San Francisco. On these
A collegue who works with time series sent me the following code snippet. He said that the calculation was overflowing and wanted to know if this was a bug in SAS: data A(drop=m); call streaminit(12345); m = 2; x = 0; do i = 1 to 5000; x = m*x
Last Friday morning I took a meeting with SAS CEO Jim Goodnight. Despite the hassle, I was happy to rearrange my busy schedule to squeeze him in. Ha! Just a little joke there about my inflated sense of importance! Actually, the meeting was part of a regular series called "Conversations
A common question really and one that I get after posting code like yesterday's All SAS Stored Process Locations Report. The neat trick is just to type METABROWSE in a BASE SAS command window. (There are two other commands: METACON and METAFIND. Has anyone got any tips on when those
Have you ever seen question marks in ODS output, diamonds with question marks in them where a copyright symbol should be, or unexpected symbols in your Web browser? In other words, do you sometimes see garbage instead of text? Manfred Kiefer’s new book, SAS Encoding: Understanding the Details can help.
Stored process code can exist within the metadata itself for version 9.3 (the benefits of which I discussed earlier). But for all other versions (and as a option in version 9.3) the SAS code is stored as a .sas file within the server's file system (or mapped folder/drive structure). When editing
The date prompt from SAS Prompt Framework provides the options of single selection or a range, however what if you need to select multiple individual dates such as Monday (May 28), Wednesday (May 30), and Friday (June 1) of last week? There are a few alternatives to accomplishing this. Option
If you are like many SAS Enterprise Guide users, you've amassed a large collection of project files (EGP files) that contain important content: programs, logs, notes, results, and more. However, to most tools and processes, the EGP file is opaque. That is, you can't see what's inside of it unless
This week's %NLINMIX macro tips come from the esteemed authors of SAS for Mixed Models, Second Edition. Ramon C. Littell, George A. Milliken, Walter W. Stroup, Russell D. Wolfinger, and Oliver Schabenberger combined their expertise to write this indispensable guide. This 800 page book has made a big impact in the user community
Did you change your LinkedIn password yesterday? (If you didn’t, you should!) But did it happen to be the same as your corporate password? First, tisk tisk. Second, change your corporate password NOW! Ok, now that this is done ~ don’t let your saved connection profile for SAS applications lock
What if you would like to make a copy of an existing stored process to test out your changes before making them live? The copy command is available from within SAS Management Console or from the SAS Enterprise Guide Open Stored Process GUI as seen below (note you can only
"Help! My simulation is taking too long to run! How can I make it go faster?" I frequently talk with statistical programmers who claim that their "simulations are too slow" (by which they mean, "they take too long"). They suspect that their program is inefficient, but they aren't sure why.
It's been two years since my first trip to SAS UK for the SAS Professionals Convention. That was also my first trip to the UK, ever. I was pretty naive back then and didn't know what to expect from this strange land and its people. I was shown tremendous hospitality
Benchmarks of forecasting performance are available from several sources, including professional organizations and journals, academic research, and private consulting/benchmarking organizations. But there are several reasons why industry forecasting benchmarks should not be used for setting your own forecasting performance objectives. 1) Can you trust the data? Are the numbers based
I recently read a blog post in which a SAS user had to rename a bunch of variables named A1, A2,..., A10, such as are contained in the following data set: /* generate data with variables A1-A10 */ data A; array A[10] A1-A10 (1); do i = 1 to 10;
In the summer of 2010, the LA Times made national waves by publishing Los Angeles Unified School District’s teacher names and value-added estimates. The New York Times followed suit in February, 2012, ranking New York City’s teachers based on their value-added ratings. While these bold actions may satisfy some parents
In the SAS/IML language, a user-defined function or subroutine is called a module. Modules are used to extend the capability of the SAS/IML language. In my blog posts, I usually define a module in a PROC IML session and then immediately use it. However, sometimes it is useful to store
My Brush With Glory The 2012 Summer [quadrennial international sporting event that isn't the World Cup] in London is just around the corner, and it's sure to be an exciting time for all. I had the good fortune to be living in the great state of Utah during the 2002 Winter [quadrennial international sporting event that
We're at stop #3 on the crash analytics highway. We've introduced the topic of the Four E's and have discussed the role of analytics in Enforcement. Now let's talk about Engineering. Safety, reliability and accessibility are all key components in road design. Traffic engineers work to make the driving environment
In the SAS/IML language, a user-defined function or subroutine is called a module. Modules are used to extend the capability of the SAS/IML language. Usually you need to explicitly load modules before you use them, but there are two cases where PROC IML loads a module automatically. Modules in IMLMLIB
Back in 2009, I announced that SAS was developing a version of its business analytics platform for use on the Nintendo Wii. I think I gave our legal department a heart attack with this news, until they realized that I had posted it on April 1. At SAS Global Forum
In a previous blog, I showed how to use SAS/IML subscript reduction operators to compute the location of the maximum values for each row of a matrix. The subscript reduction operators are useful for computing simple statistics for each row (or column) of a numerical matrix. If x is a
SAS Dress Code In addition to providing great software for forecasting (and business analytics in general), SAS is also renowned as a great place to work. (See #1, #1, and #3 rankings the past three years in the Fortune 100 Best Companies to Work For.) Part of this greatness is due
