For supply chain managers and analysts Getting Demand in Shape can mean collecting the most pertinent data to support specific business processes and activities. Identifying new or previously unused data sources can be especially important. My most recent article titled “Getting Demand in Shape” in the May / June issue of APICS magazine
Nonlinear optimization routines enable you to find the values of variables that optimize an objective function of those variables. When you use a numerical optimization routine, you need to provide an initial guess, often called a "starting point" for the algorithm. Optimization routines iteratively improve the initial guess in an
Now, the Star-Belly Sneetches Had bellies with stars. The Plain-Belly Sneetches Had none upon thars. - from "The Sneetches", by Dr. Seuss Recently a user on the SAS-L mailing list had this challenge: "I would like to display stars in a table (created by PROC REPORT) based on variable values.
This is part 3 of a blog series on how Lubbock Independent School District (Lubbock ISD) uses SAS® EVAAS to improve teaching and learning by promoting self-reflection and aiding instructional and administrative decision-making. This is done in a district that, in the past decade, has experienced dramatic increases in the percentage
When teaching statistics, it is often useful to produce a normal density plot with shading under the curve. For example, consider a one-sided hypothesis test. An alpha value of .05 would correspond to a Z-score cutoff of 1.645. This means that 95% of a standard normal curve falls below a

Predictive analytics is changing the way the public sector prevents fraud by helping to stop it before it happens. I interviewed Ian Pretty of Capgemini at the Analytics 2014 conference in Frankfurt about how the government is using analytics and why it’s important. For more videos from the conference,
Principle 10: Frequency – The board and senior management (or other recipients as appropriate) should set the frequency of risk management report production and distribution. BCBS 239 “Effective Risk Data Aggregation & Risk Reporting”, released in January of 2013, specifically requires that the bank’s board and senior management should be
In many areas of statistics, it is convenient to be able to easily construct a uniform grid of points. You can use a grid of parameter values to visualize functions and to get a rough feel for how an objective function in an optimization problem depends on the parameters. And
“Technological innovation is no longer a choice: it is an imperative.” So said Scott O’Malia, Commissioner of the Commodity Futures Trading Commission, about trade surveillance during his keynote address at the recent SAS-sponsored New Risk in Energy 2014 conference in Houston. He was attempting, as he has before, to spur
How Internal Communications got into the video business. Everybody loves video. Well, maybe not everybody, but judging by the popularity of YouTube and the ubiquity of Web videos in general, I’d have to conclude that a mighty large chunk of the population loves – or at least likes – it.
Oil companies are being forced to explore in geologically complex and remote areas to exploit more unconventional hydrocarbon deposits. New engineering technology has pushed the envelope of previous upstream experience. No guidebook existed on how computing methodologies can contribute to E&P performance at reduced risk. Until now. A new book

La posibilidad y necesidad de acceder a la información desde cualquier sitio, en cualquier momento y con prácticamente cualquier dispositivo, ha
We asked Lars George, EMEA Chief Architect at Cloudera, to share his opinion about Hadoop, Big Data and future market trends in Business Analytics. For all those who want to know more about Hadoop we recomment this TDWI whitepaper and how to apply Big Data Analytics. The last few years
El uso de soluciones analíticas para la creación de servicios optimizados centrados en el cliente es moderado en el sector bancario, contrario a otros sectores que incrementan sus servicios con la generación de productos hechos a la medida de sus consumidores. Al respecto, una encuesta realizada por la empresa de
Improving teacher effectiveness is no simple task. Whether a part of a formal evaluation system or for formative feedback, looking at student growth data can be a valuable part of the development process for teachers and administrators. Lubbock Independent School District (Lubbock ISD) uses SAS® EVAAS to improve teaching and
In my book Simulating Data with SAS, I specify how to generate lognormal data with a shape and scale parameter. The method is simple: you use the RAND function to generate X ~ N(μ, σ), then compute Y = exp(X). The random variable Y is lognormally distributed with parameters μ
We're entering the busy season for forecasting events, and here is the current calendar: Analytics2014 - Frankfurt The European edition of Analytics2014 kicks off tomorrow in Frankfurt, Germany. Five hundred of the leading thinkers and doers in the analytics profession hook up for two full days of interaction and learning.
The Analytics 2014 conference in Frankfurt, Germany gets started tomorrow, but today many of the speakers and attendees are arriving at the Frankfurt Marriott. I caught up with Beth Schultz, editor-in-chief of AllAnalytics.com to hear about her keynote presentation and to find out the benefits of being part of the
This blog post describes a neat example of some cool SAS capabilities, and also teaches you a little more about the state where SAS software is made... Here at the SAS headquarters in Cary, NC, the main TV news channel is WRAL TV5. And my favorite segment during the news is Scott
So, what is the most unusual place that you have had SAS? Okay, I admit it; I used a somewhat provocative title and lead sentence to get you to read this blog. It must have worked because here you are. But, do not worry; there are no hidden meanings, untoward
Insights from decision trees and other basic analytic techniques show that you don’t always need complex analytics to solve business problems and add value. This was the message from Dr. James (Jim) Foster, Director of Research and Process Development, Archer Daniels Midland (ADM), at last month’s inaugural IE Group ‘Manufacturing Analytics
Principle 9: Risk management reports should communicate information in a clear and concise manner. Reports should be easy to understand yet comprehensive enough to facilitate informed decision-making. Reports should include meaningful information tailored to the needs of the recipients. While the data management and data aggregation principles have been heavily
Sometimes you have data in SAS/IML vectors that you need to write to a SAS data set. By default, no formats are associated with the variables that you create from SAS/IML vectors. However, some variables (notably dates, times, and datetimes) should have formats associated with the data values. You can
I wish I had a nickel for every time I heard this question at SAS Global Forum: "So, does this SAS Studio thing replace SAS Enterprise Guide?" SAS Studio is a pretty big deal. It's groundbreaking in several ways: It's a web-based programming interface to SAS. It runs in your
Bootstrap methods and permutation tests are popular and powerful nonparametric methods for testing hypotheses and approximating the sampling distribution of a statistic. I have described a SAS/IML implementation of a bootstrap permutation test for matched pairs of data (an alternative to a matched-pair t test) in my paper "Modern Data
La gestión de datos es la práctica que permite a las empresas organizar y administrar los datos como un activo valioso e impulsar tanto los principales procesos operativos, como la toma de decisiones estratégicas al interior de las organizaciones. El gobierno de datos, entre tanto, hace referencia al esquema de
Da war doch mal was, Sie erinnern sich, Hoodiejournalismus?! In dieser Diskussion über Digital gegen Print, jung gegen alteingessen, #hoodie vs. #schlipsy, über was ist Premium oder was ist hautnah dabei, über was erscheint modern, zeitgemäß und innovativ oder was bezahlt die Miete am Ende des Monats, ist ein Punkt
A little-known but useful feature of SAS/IML 12.3 (which was released with SAS 9.4) is the ability to generate a vector of lowercase or uppercase letters by using the colon operator (:). Many SAS/IML programmers use the colon operator to generate a vector of sequential integers: proc iml; x =
Principle 8: Comprehensiveness - Risk management reports should cover all material risk areas within the organization. The depth and scope of these reports should be consistent with the size and complexity of the bank’s operations and risk profile, as well as the requirements of the recipients. One of the four
