About the Webinar
This one hour webinar will begin at 10 am ET and provide a simple overview on the common uses and fundamental assumptions behind Ordinary Linear Regression (OLR), followed by an explanation on why the ReXY-based technique in ASTM D6708 Practice for Statistical Assessment and Improvement of Expected Agreement Between Two Test Methods that Purport to Measure the Same Property of a Material should be used instead of OLR to develop correlation between two methods that claim to measure the same property. The D6708 process, inputs, outputs, and failure modes will be presented.
Who Should Attend
This webinar is intended for Lab Chemists, Process Analyzer and Control Engineers involved in or interested in developing a correlation between two technically different analytical test methods that claim to measure the same property, with the goal of using the correlation applied to one method as a surrogate or predictor for the other method.
How to Register
The fee is $150 per person. After registering, you will receive an email ten days prior to the webinar with information about how to access the webinar. In addition to the webinar, you'll get 7-day access to a recording of the session.
About the Instructor
Alex T. Lau is the Chair of ASTM D02.94 Subcommittee on Quality Assurance and Statistics, D02.01.0B on Precision, and Vice Chair of Subcommittee D02.25 on Validation of Process Stream Analyzer Systems. He has 40 years experience in the Petroleum Refining Industry. An ASTM International member since 1990, he is also an active member of Committees E11 on Quality and Statistics. He retired from Imperial Oil, Canada (an ExxonMobil affiliate), and formed his own consulting company (TCL-Consulting). His career focus specialized in gasoline and diesel fuel blending, direct blend to pipeline and ships, on-line process analyzer applications, statistical techniques for quality assurance and process improvement, development and implementation of industry standards.
He is the recipient of the ASTM International Award of Merit, ASTM D02 Scroll of Achievement, and several Awards of Excellence. Lau was cited "for outstanding contributions in Committee D02 on Petroleum Products and Lubricants and Coordinating Subcommittee D02.94 on Quality Assurance and Statistics toward standards development, both as an individual contributor and leader."
He graduated from the University of Toronto with a Bachelor's degree in Applied Science and Engineering Physics. Outside of ASTM International, Lau is a member of the Professional Engineers of Ontario (PEO) and the American Society for Quality (ASQ). He is a registered Professional Engineer in Ontario, Canada, and an ASQ Certified Quality Engineer. He is also the Convener of ISO TC28 / WG2 on Statistics.
