From fuel shortages at petrol stations to the terrifying prospect of a Christmas turkey shortage, we’ve suddenly become aware of how precarious our society is, and how quickly we can slip from order into chaos. Of course, for anyone working in the utilities sector, this is hardly news. But supply chain risk has never been more apparent to the public, as sudden rises in wholesale gas prices have played havoc with the ... Read More

A large part of that value is keeping your data safe and secure in the SAS Cloud because let’s face it: Analytic solutions are only as good as the data stored in them. That’s where Randy Wilcox and Ken Persson come in to help you with their respective SAS Cloud teams: the data platforms team and the extract, transform and load (ETL) operations team. Randy Wilcox, Global Leader of Data Platform Technologies ... Read More

Mas se os superarmos, a recompensa será ainda maior. Meu primeiro projeto de Ciência de Dados foi ainda durante minha graduação em Estatística. Embora não tivesse esse nome à época, o objetivo e os meios eram os mesmos: auxiliar no processo decisório por meio de modelos preditivos. Embora as palavras-chave que descrevem a transformação de dados em ações tenham mudado muitas vezes nas últimas décadas, o suporte à decisão sempre pareceu a motivação final. Mais de 12% da força ...

As defined in the SAS® 9.4 Stored Processes: Developer's Guide, Third Edition, a stored process "is a SAS program that is stored on a server and defined in metadata, and which can be executed as requested by client applications." One of the benefits of using stored processes is that client applications always have the latest version of the code. In addition, stored processes provide enhanced security and application integrity. Have you ever ... Read More

I had heard that some countries still use a lot of coal (especially those countries with large coal deposits), and I was curious which countries use the most coal. And it seemed like a good potential topic for some graphs... Follow along, and maybe you'll learn a little something about coal, or maybe you'll learn some tricks to help you graph similar data! And here's a random coal-picture to get ... Read More

I'm not sure when it started, but I've had this lifelong situation that began small, I'm sure, and then grew!  While I've encouraged it to become a friend, some days it is not.  You may ask who or what this friend is.  It's a little thing called perfectionism.  It can make life a bit more challenging to meet goals, get things done in an orderly fashion (like writing this article) and being our best selves.   Does this sound familiar? Are you wondering if you have it? Some of us ... Read More

Feed: SAS Blogs. Author: Rick Wicklin. A genetic algorithm (GA) is a heuristic optimization technique. The method tries to mimic natural selection and evolution by starting with a population of random candidates. Candidates are evaluated for "fitness" by plugging them into the objective function. The characteristics of the better candidates are combined to create a new set of candidates. Some of the new candidates experience mutations. Eventually, over many generations, a GA can produce candidates that approximately solve the optimization problem. This article uses SAS/IML to implement a genetic algorithm in SAS. A previous article discusses the ... Read More

In this Q&A with MIT/SMR Connections, Iain Brown, SAS’s head of data science for the United Kingdom and Ireland, discusses some key risks, ethical issues, and platform questions that organizations should consider before adopting AI and takes a quick look at current and emerging AI trends. Q: In your view, what are some of the biggest risks associated with the development of AI solutions? Iain Brown: In my view, the biggest risk we see today is how transparent the process leading up to an AI-derived decision is. It’s all too easy for AI to ... Read More

Then there’s the Amazon effect, which has led to sky-high consumer expectations of the ordering and delivery process. Demand planners for retailers and consumer goods companies have quickly realized they have no real view into consumer demand and are not able to react to shifting consumer demand patterns. The demand planning journey Figure 1: Level Up Your Demand Planning Infographic Demand planning is vitally important to the profitability of retail, consumer goods and manufacturing organizations.
