Suppose you roll six identical six-sided dice. Chance are that you will see at least one repeated number. The probability that you will see six unique numbers is very small: only 6! / 6^6 ≈ 0.015. This example can be generalized. If you draw a random sample with replacement from

Summer is here, which means vacations and time at the pool with a good book. If expanding your knowledge is a goal of yours this summer, SAS has a shelf full of new titles becoming available over the next few months. From new editions of classics – such as SAS® for Forecasting
I've found that when supporting others it can be helpful to simply normalize that it's ok to feel two things at once. Usually, one of the two is more "taboo". "Of course you are feeling disappointed by your friend's actions. Being disappointed doesn't mean you are not appreciative of the positive aspects of your friendship." "Of course you
Let me start by posing a question: "Are you forecasting at the edge to anticipate what consumers want or need before they know it?" Not just forecasting based on past demand behavior, but using real-time information as it is streaming in from connected devices on the Internet of Things (IoT).
In a previous blog, I demonstrated a program and macro that could identify all numeric variables set to a specific value, such as 999. This blog discusses an immensely useful technique that allows you to perform an operation on all numeric or all character variables in a SAS data set.
Matthew Magne describes how SAS Data Quality can help you build a trusted data foundation, one stone at a time.
When I teach my Data Cleaning course, the last topic I cover in the two-day course is SAS Integrity Constraints. I find that most of the students, who are usually quite advanced programmers, have never heard of Integrity Constraints (abbreviated ICs). I decided a short discussion on this topic would
You can use a range attribute map to control the mapping of values in a continuous variable to colors. This post shows you how to use PROC SGPLOT to display multiple plots in the same graph and use range attribute maps.
The role of analytics in combating terrorism Earlier this spring, I found myself walking through a quiet and peaceful grove of spruce trees south of the small hamlet of Foy outside of Bastogne, Belgium. On travel in Europe, I happened to have some extra time before heading to London. I
Negli ultimi anni l'uso sempre più diffuso di sofisticati modelli matematici, statistici e deterministici ha consentito alle istituzioni finanziarie di prendere decisioni strategiche, avendo a disposizione un nuovo livello di conoscenza. Nel contempo ha, però, condotto verso una nuova necessità: quantificare, misurare e gestire il rischio legato ai modelli utilizzati.
The new government’s vision of Brexit is to make the UK a more international, more outward looking nation. One whose future success and status in on the world stage will be dictated by the ability to attract investment and finance, and to drive trade with existing and new partners. Yet
My presentation at SAS Global Forum 2017 was "More Than Matrices: SAS/IML Software Supports New Data Structures." The paper was published in the conference proceedings several months ago, but I recently recorded a short video that gives an overview of using the new data structures in SAS/IML 14.2: If your
To demonstrate the power of text mining and the insights it can uncover, I used SAS Text Mining technologies to extract the underlying key topics of the children's classic Alice in Wonderland. I want to show you what Alice in Wonderland can tell us about both human intelligence and artificial
Science-Fiction-Autoren sind seit Langem fasziniert von der Vorstellung, dass Roboter die Weltherrschaft übernehmen könnten. Und sie überlegen, was man tun könnte, um die Welt vor dieser Machtübernahme zu bewahren. Doch diese Vorstellung geht weit an der Realität vorbei. Tatsächlich wissen wir heute: Maschinen – und Machine Learning – funktionieren am
