Q: How would you set the target for demand planners: all products at 0.7? All at practical limit (0.5)? A: In principle, forecasts are capable of being brought to the practical limit of an RAE of 0.5. Whether it is sensible to attempt to do this for all products irrespective
Principle 2: Data architecture and IT infrastructure – A bank should design, build and maintain data architecture and IT infrastructure which fully supports its risk data aggregation capabilities and risk reporting practices not only in normal times but also during times of stress or crisis, while still meeting the other
The SAS Users Groups Leaders meet-up was scheduled for the last evening of SAS Global Forum 2014, sandwiched between the last of the Tuesday presentations and the Kick-Back Party later that evening. There were a few familiar faces from regional users groups but lots of new ones from local and
I enjoy blogging about new functionality in the SAS/IML language because I can go into more depth and provide more complicated examples than the SAS/IML documentation. Today's article is a summary of all of my posts about features that were added to SAS/IML 12.1, which shipped in August 2012 as
When you hear of a Scatter Plot or a Series Plot, you have a picture in your mind what we are talking about. But one of the plot statements available in GTL, and soon with SGPLOT, is the BLOCK plot. I am sure this leaves many users scratching their heads, wondering
In this tutorial video, you will learn to print a simple listing with Base SAS. You see how to write a PRINT procedure step to display a SAS data set. You also see how to use statements and options to subset observations and variables and enhance the report. Learn
So far in this Ask the Statistician series, we heard statisticians at the Analytics 2013 conference discuss the benefits of statistical analysis, the types of statistical techniques they use to solve their business problems and how they share their statistical results with non-technical audiences that need to use this information. So, the next step
This is a question I get pretty often. It’s not an easy question to answer either. It depends on what your goal is. Do you want a milk that’s low in calories or do you want one that’s high in protein? Maybe taste is your only criteria. Luckily, if you
It was wonderful to see and talk with so many SAS Administrators at SAS Global Forum this year. If you’re like me, you may have finished the conference wondering why it wasn’t possible to be two places at once because there was so much terrific content that it was impossible
The Hilbert matrix is the most famous ill-conditioned matrix in numerical linear algebra. It is often used in matrix computations to illustrate problems that arise when you compute with ill-conditioned matrices. The Hilbert matrix is symmetric and positive definite, properties that are often associated with "nice" and "tame" matrices. The
Technology and software, much like SAS, makes everything simpler and more accessible. To fully appreciate what a company like SAS embodies and what it has to offer a student, I feel it is essential to attend SAS Global Forum, especially if analytics is something that drives you. Attending a conference
The volume is being turned up on the Control Tower approach to running a business; I have recently been introduced to logistics control towers, supply chain control towers and operations control towers just for starters. I’m sure there must be at least a half dozen more out there – pick
With all the changes the Affordable Care Act brings, including new care and payment models, there is an increase in provider’s need for data. While some large health systems are able to learn much about a patient’s full course of treatment by integrating their systems, the majority of health care
Principle 1: Governance – A bank’s risk data aggregation capabilities and risk reporting practices should be subject to strong governance arrangements consistent with other principles and guidance established by the Basel Committee. My colleagues and I have written a series of posts on the principles of BCBS 239. In this
The GCHART procedure has a popular option called G100 to display all the subgroups in % format such that all the subgroup values add up to 100% for each group. Each subgroup is labeled with its own % values. SGPLOT procedure does not such an option, but with a little bit of
