SAS Support Communities provide a forum in which to engage and share with your fellow SAS experts, now in over 20 topic areas including Forecasting and Econometrics. This is the go-to website for your hard core modeling questions, such as "Holdouts in PROC ARIMA," "2-stage Heckman (1979) procedure," and the
As 2014 slowly winds down it’s time to gear up for the holiday shopping rush. As in recent years the Consumer Electronics Association reports tech gifts will again be high on everyone’s list this holiday shopping season. A new addition to the list this year are numerous Internet of Things
Just a reminder that on Wednesday, December 3, 10:00am ET, Paul Goodwin will be delivering the next Foresight/SAS Webinar on "Getting Real About Uncertainty." From the description: Many forecasts only tell us about things like probable events, expected sales and prospective demand. Often they tell us nothing about the level
The bigness of your data is likely not its most important characteristic. In fact, it probably doesn’t even rank among the Top 3 most important data issues you have to deal with. Data quality, the integration of data silos, and handling and extracting value from unstructured data are still the most
I have probably touched on this topic many times before: accessing the data that has been loaded into a master data environment. In recent weeks some client experiences are really highlighting something that is increasingly apparent (and should be obvious) for master data management: the need to demonstrate that it
There are multiple types of data models, and some companies choose to NOT data model purchased software applications. I view this a bit differently. I think that any purchased application is part of our enterprise, thus it is part of our enterprise data model (or that concept is part of the
Perhaps it’s the same for you - it’s getting harder to get to all the conferences I’d like to attend. One of the benefits of getting out there is a chance to learn about different perspectives in an industry. When someone has a broad perspective, particularly if they’ve been in
A common question on SAS discussion forums is how to compute the minimum and maximum values across several variables. It is easy to compute statistics across rows by using the DATA step. This article shows how to compute the minimum and maximum values for each observation (across variables) and, for
When you examine where most data quality defects arise from, you soon realise that your source applications are a prime culprit. You can argue that the sales team always enter incomplete address details, or the surgeons can't remember the correct patient type codes but in my experience the majority of
Calling All Forecasters Have you tried Forecast Value Added analysis? What did you find out? Are you willing to share your learnings (at least those that can be revealed publicly)?Would you like to be featured in a new blog series on FVA, published by the Institute of Business Forecasting? The IBF was
‘Tis the day before T-Day and all through the mall The shoppers are waiting for prices to fall. The signs they are printed and ready to hang In hopes that “Black Thursday” will start with a bang. The family has traveled and all gathered here To spend time with grandma
I generally don’t use this blog to air my personal experiences, but recent events have reminded me of a few things that I think would benefit our Analytic Hospitality Executives and their organizations to also be reminded of. This past week, I took my fifth trip to Asia this year.
Data. Our industry really loves that word, making it seem like the whole world revolves around it. We certainly enjoy revolving a lot of words around it. We put words like master, big, and meta before it, and words like management, quality, and governance after it. This spins out disciplines
Un Chief Information Officer tiene ciertas características que lo hacen desempeñarse dentro de un rol único. Sin embargo, gracias a los retos que conlleva ahora la implementación de proyectos de analítica avanzada en las organizaciones, han surgido algunos mitos que rodean el rol de TI. Keith Collins, Vicepresidente Senior de
I've written about how to generate a sample from a multivariate normal (MVN) distribution in SAS by using the RANDNORMAL function in SAS/IML software. Last week a SAS/IML programmer showed me a program that simulated MVN data and computed the resulting covariance matrix for each simulated sample. The purpose of
Having worked in analytics for over 25 years, I’ve never really felt part of the ‘cool gang’. However that’s changing and all of a sudden, at long last, it is "chic to be geek!" Research published by SAS UK and the Tech Partnership reveals that from 2013 to 2020, the
A lack of mental health professionals is pushing the US mental health system to a crisis point. And even if a psychiatrist commits someone to a facility, there may not be a bed for them. A startling 55 percent of all US counties have zero psychiatrists, psychologists or social workers
Can you spare a few minutes to assist researchers at the Lancaster Centre for Forecasting? We have been commissioned by the European Journal of Operational Research to write a review article on Supply Chain Forecasting. In undertaking this task, we would like to ensure that the topics covered reflect the priorities
For many industries, big data analytics have opened numerous doors for more employees to be groundbreaking and to challenge the corporate status quo. Prior to big data technologies, risk taking behaviors were primarily reserved for provocative souls who stretched organizational boundaries to disrupt industries, such as airline revenue management. There were winners and losers
Don't be shy! Interviewing people BEFORE or AFTER a facilitated session just takes a bit of confidence, and good preparation. Building your confidence gets easier and easier the more you participate in interviews. The objective is to prepare and not waste anyone’s valuable time. I like to prepare notes based on
SAS software contains a lot of features, and each release adds more.To make sure that you do not miss new features that appear in the SAS/IML language, the word cloud on the right sidebar of my blog contains numbers that relate to SAS or SAS/IML releases. For example, you can
Well, this is a kick to the giblets. I assumed when I was summoned to the White House it was in recognition of my tireless advocacy for turkey rights. I wasn’t expecting a press conference in the rose garden or anything, just a meet and greet with the prez and
„Wieder ein Berater, wieder ein Systemintegrator, wieder ein Outsourcer und wieder ein Software- oder Hardware-Hersteller, der mir erzählt, dass Big Data der Trend der Zukunft ist. Jeder erzählt mir, wie wichtig „Big Data“ für mein Unternehmen sind. Und wenn ich hier nicht zustimme, bin ich gleich ein Innovationsverweigerer. Die Nachfrage
Not all fraud originates from the dark underground of criminal enterprises. In fact, fraud could literally be right under our noses, or in the cubicle next to us. The “Insider Threat” has many names – internal fraud, occupational fraud, even espionage – and uses authorized internal access and knowledge to
Every day there are news stories of fraud perpetrated against federal government programs. Topping the list are Medicaid and Medicare schemes which costs taxpayers an estimated $100 billion a year. Fraud also is rampant in other important federal programs, including unemployment and disability benefits, health care, food stamps, tax collection,
Many managers still perceive data quality projects to be a technical endeavour. Data being the domain of IT and therefore an initiative that can be mapped out on a traditional project plan with well-defined exit criteria and a clear statement of requirements. I used to believe this myth too. Coming
My colleagues at the SAS & R blog recently posted an example of how to program a permutation test in SAS and R. Their SAS implementation used Base SAS and was "relatively cumbersome" (their words) when compared with the R code. In today's post I implement the permutation test in
Last week I had the opportunity to attend the INFORMS Annual Meeting in San Francisco. For those of you not familiar with this organization or conference, the Institute for Operations Research and the Management Sciences (INFORMS) is the largest society in the world for professionals in the field of operations
Hadoop recently turned eight years old, but it was only 3-4 years ago that Hadoop really started gaining traction. It had many of us “older” BI/DW folks scratching our heads wondering what Hadoop was up to and if our tried-and-true enterprise data warehouse (EDW) ecosystems were in jeopardy. You didn't
When it comes to fraud detection and risk mitigation, predictive modeling has earned a reputation as the “heavy hitter” in the realm of data analytics. As our celebration of International Fraud Awareness Week continues, I would challenge our readers to ask themselves this question, “Is the reliance upon predictive analytics
