In trying to offer better support to SAS users, many customers’ IT departments are looking to consolidate all their SAS desktop users onto a centralized Windows, UNIX or Linux server. This option is a very practical strategy, but implementing it satisfactorily requires a lot of assessment on how the SAS
What Kind of Holidays Do You Want? Do you like your holiday filled with lots of parties or do you prefer a quiet walk in the woods with a friend? Do you love bumping elbows with thousands of shoppers at the mall or relaxing at home with family? These are good
Last time I suggested that there are some typical use cases for master data, and this week we will examine the desire for accessibility to a presumed “golden” record that represents “the single source of truth” for a specific entity. I put both of those terms in quotes because I
December is all about traditions. Some of mine include holiday shopping, baking (I really mean eating) Christmas cookies and putting together my annual list of most read blogs on the SAS Training Post. So as traditions go… here’s my list of the top 10 most read blogs in 2014. How
Congratulations if you’re one of the over 300 presenters whose proposals for content were accepted for SAS Global Forum 2015! Now that it’s time to start preparing papers, posters and presentations, I thought this would be a good opportunity to write about the Presenter Mentoring Program, an excellent service offered
Last week I discussed factors that threaten access to mental health care. However, better access to care doesn’t always mean better quality of care. Overworked mental health professionals and overcrowded ERs are forced to expend efforts and limited resources where they have the most impact. This forces compromises in care.
To perform a successful data conversion, you have to know a number of things. In this series, we have uncovered the following about our conversion: Scope of the conversion Infrastructure for the conversion Source of the conversion Target for the conversion Management for the conversion Testing and Quality Assurance for
There are many ways to multiply scalars, vectors, and matrices, but the Kronecker product (also called the direct product) is multiplication on steroids. The Kronecker product looks scary, but it is actually simple. The Kronecker product is merely a way to pack multiples of a matrix B into a block
A common scenario is where we have a table of multiple measures over time. Here we have a simple example of Frequency and Response by Day. The Response is a linear function of the Frequency, as shown in the table on the left below. The shape of the data is
I recently found some very interesting data - a numeric Corruption Perceptions Index for each country. And of course I just had to try and create my own SAS version... First, here's the original map on the transparency.org site. They mapped all the values using a yellow-orange-red gradient, the map
We are in the age of big data. But just because modern software makes it easy to handle large data volumes, it's worth asking: do you always need all that data? In other words, if your analytics software can accommodate and even thrive in this big data environment, does that mean
Here on the Data Roundtable we've discussed many topics such as root-cause analysis, continual improvement and defect prevention. Every organization must focus on these disciplines to create long-term value from data quality improvement instead of some fleeting benefit. Nowhere is this more important than the need for an appropriate education strategy, both in
In a recent post, I talked about the 5 essential characteristics of cloud computing. In today’s post, I will cover the three service models available in the cloud as they are defined by the National Institute of Standards and Technology, or NIST. Like the story of Goldilocks, when it comes
As teachers across 35+ states are evaluated, and sometimes compensated, in part by the academic growth of their students, there may be an unintended consequence. Teachers may question whether to accept student teachers, in fear of the student teacher bringing down their value-added estimate(s) and overall evaluation rating. How can
A student in a SAS class recently asked if there were a way to eliminate data error notes from the SAS log and, instead, write them to a separate file. Of course there's a way! Here's a simple datastep. Notice the missing dollar sign to indicate the variable GENDER (M,
