"I consider Rexer Analytics’ surveys one of the best independent analyses of Data Mining.  I stress the word ‘independent’ as that is the most useful.  Karl and his team have been active in this market for many years and bring considerable experience to the topic."

John MacGregor, Vice President, Customer Innovation & Strategic Projects, Products & Innovation, SAP;  Author of “Predictive Analysis with SAP: The Comprehensive Guide”

"Rexer Analytics has been instrumental in helping advance the field of data mining through applied research, software evaluation, testing, professional conference support and consulting.  Their research evaluating the trends and preferences among the data mining community is a great resource for many."

Wayne Thompson, PhD;  Chief Data Scientist, SAS

"The Rexer Analytics Data Mining Survey provides valuable insight into trends in tools and techniques, as well as backgrounds of data mining practitioners.  Rexer's analysis of the survey data dives into hype or reality of big data to the rise of analytics software like R, as well as challenges faced by analysts and their job satisfaction.  I look forward to each survey's results and increasingly see these results highlighted in presentations from other well-respected experts in the field."

"The Data Science Survey is one of the few unbiased resources that provides a comprehensive overview of the data science community.  It is a key source of information for analytic professionals regarding vendors, tools, and state-of-the-art algorithms.  As a frequently cited publication, it covers essential topics, new trends like “big data”, as a well as general market surveillance."

Michael Zeller, PhD;  CEO, Zementis

"The Rexer Analytics Data Miner Survey is the best survey of the current state and direction of the data mining and predictive analytics industry.  I recommend it to my workshop and course attendees regularly as a way to understand the important trends in software, algorithms, job titles, and vertical markets, as well as issues impacting the analytics industry and which buzz words are gaining traction."

Karl Rexer was one of four industry leaders at the 2017 Oracle BIWA Summit selected to be interviewed on theCUBE. TheCUBE is the flagship show of SiliconANGLE Media and a leading live interview show covering enterprise technology and innovation.

"Rexer Analytics is definitely one of the key players in the Data Mining ecosystem.  I was introduced to the world of data science when I attended Karl’s Hands-on Lab at the 2008 Oracle BIWA Summit.  In addition to the software training, Karl spent extra time with me, answering questions and providing implementation advice.  Karl is one of the organizers of the annual BIWA Summit, and it is an outstanding event.  Each time I bring my analytic team.  We look forward to talking with Karl and others, sharing our successes, discussing ways to overcome challenges, and learning new things.  Karl’s original Oracle Data Miner training session got us started -- and in the subsequent years our Risk Analytics team has tackled tough business challenges, and been very successful in fighting e-payments fraud.  Rexer Analytics is the go-to team to help create analytic solutions."

"Karl has generously dedicated a great amount of time and energy to helping my students succeed – by being a frequent guest speaker in undergraduate and MBA business analytics classes, by serving on the industry advisory board that helped shape Babson’s undergraduate and MBA business analytics concentrations, and by advising individual students on careers in data science and business analytics.  The depth and breadth of his experience and knowledge are evident, and have been helpful to both students and faculty at Babson."

"The Rexer Analytics team has a passion for data mining.  This is illustrated by their outstanding Data Miner Survey research, and the contributions of time and expertise they make to professional organizations and conferences.  I first met Karl when we both served on the KDD-2006 conference organizing committee.  He has worked on a number of international data mining conferences, and been instrumental in soliciting sponsors, reviewing papers, judging best paper prizes, and teaching hands-on labs.  I have been involved with INFORMS for many years, and was happy to see Karl jump at my offer to participate.  He spoke at a local INFORMS chapter, encouraged others to attend INFORMS conferences, and he and his team wrote an article for the INFORMS ‘Analytics Magazine.’  My data scientist colleagues and I applaud the contributions of Rexer Analytics."
