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

A new book from SAS guides public sector leaders in the use of data to address a wide range of state and local government challenges. Each chapter deals with critical issues facing our country, including the opioid epidemic, child abuse, spiraling health care costs, prison overcrowding, education reform, rampant fraud and the
La primera vez que alguien se refirió al Internet de las Cosas fue en 1999 y se trató del emprendedor Kevin Ashton, uno de los fundadores del centro Auto-ID en el MIT, quien lo acotó durante una presentación sobre la posibilidad de vincular objetos a través de la identificación por
Dictionary tables are one of the things I love most about SQL! What a useful thing it is to be able to programmatically determine what your data looks like so you can write self-modifying and data-driven programs. While PROC SQL has a great set of dictionary tables, they all rely
La vida de un infante es frágil y cuelga de un delgado hilo. Desde los recién nacidos prematuros hasta los bebés con meses de edad que luchan con problemas médicos, las unidades de cuidados intensivos neonatales (UCIN) tienen que estar preparadas para todo. Es por eso que los médicos, las
