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
Puede llamarlo transformación, cambio de paradigma, evolución o revolución. No importa qué nombre reciban: en la actualidad, los servicios en la nube están cambiando la realidad de los negocios. 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.
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
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
As a follow up to my previous post that described analytics in one word, I decided to revisit my choice of the word "strategic" with a video. If the adage "a picture is worth a thousand words" is true, you'll like this version even better than the original. Watch the video
So far in our Ask the Statistician blog and video series, we have heard responses from statisticians at the Analytics 2013 conference about: The many ways statistics benefit their organizations. The types of statistical analyses used to solve business issues. Best practices for explaining results. How they put statistical
In a previous post, I stated that you should avoid matrix multiplication that involves a huge diagonal matrix because that operation can be carried out more efficiently. Here's another tip that sometimes improves the efficiency of matrix multiplication: use parentheses to prevent the creation of large matrices. Matrix multiplication is
Do you ever look at a chart or graph and think about what it’s really trying to reveal? All the time, right? Visualizations are useful because they allow us to analyze information much quicker than if we were to look at the raw data by itself. I say this with
Principle 7: Accuracy - Risk management reports should accurately and precisely convey aggregated risk data and reflect risk in an exact manner. Reports should be reconciled and validated. Successful demonstration of Principle 7 requires senior management to rely upon the information presented in risk reporting. Since forward-looking strategic decisions are
I love working with SAS Technical Support because I get to see real problems that SAS customers face as they use SAS/IML software. The other day I advised a customer how to improve the efficiency of a computation that involved multiplying large matrices. In this article I describe an important
Data federation is a relatively new term used to describe a form of data virtualization. Data virtualization, however, is not new. It has been around since at least the 1960's when virtual memory was introduced to simulate additional memory beyond what was physically available on a machine. While data federation is a
Imagine this scenario: Every device we encounter in our day-to-day routine – from our refrigerators and automobiles to our water and gas meters – has embedded sensors that read real-time information and generate unfathomable amounts of data. Now take this scenario one step further. Imagine what kinds of insights we’d
A recent Charlotte Observer article provided a thoughtful investigation of growth and achievement in North Carolina’s Charlotte Mecklenburg Schools). The article juxtaposed two very different, yet highly effective, schools. The first, Ranson Middle School, is a low-achieving school with 84% poverty that demonstrated the highest academic growth of any similar
Las crisis financieras han ocurrido desde los inicios de la historia mundial y forman parte de la naturaleza de los ciclos económicos. Es casi imposible evitarlas, pero sí se pueden desarrollar mecanismos de control y prevención que permitan al sistema financiero fortalecerse y mitigar sus efectos y propagación. Según Javier
In light of the recent reports that glaciers in Antarctica are melting, what SAS graphs might be useful in analyzing the data?... When floating sea ice melts (such as at the North Pole), it doesn't raise the sea level - but when ice on land melts (such as glaciers at
My previous post made the point that it’s not a matter of whether it is good for you to use samples, but how good the sample you are using is. The comments on that post raised two different, and valid, perspectives about sampling. These viewpoints reflected two different use cases for data,
