John Sall leads the JMP business unit at SAS and remains the chief architect of JMP statistical discovery software. JMP has been a part of SAS since the first version of JMP was launched in 1989, bringing interactive data visualization and analysis to the desktop.
In semiconductor data, it is common for probe measurements that encounter an electrical short to exhibit measurements that are far out in the distribution, i.e., they are outliers. When we test that means are the same, these outlying values inflate our estimate of the standard deviation [sigma]. Remember that the
Purely random data has a 5% chance of being significant. Choose the most significant p-values from many tests of random data, and you will filter out the tests that are significant by chance alone. Suppose we have a process that we know is stable and consistent. We measure lots of

Note: JMP 11 launched last week. Today, we begin a series on Tuesdays of Big Statistics blog posts by John Sall about what has to change when you have Big Data, with an emphasis on screening. Data preparation is a big part of an analyst’s job, and when you have

JMP 10 is a major release, and today we are launching it with live webcasts in four languages. I wanted to offer some reflections on what this new version is like. Much of the development centered on four focus areas: 1. Graph Builder everywhere. The Graph Builder platform has been
Journal of Quality Technology has appointed Bradley Jones as its new editor starting next year. JQT is a journal published by ASQ that emphasizes applied techniques in industrial statistics, including experimental design, Brad’s specialty. Brad’s current role at SAS is Principal Research Fellow at JMP, where he develops software for
Today SAS Institute had a huge double play of publicity. On the same day, we (1) learned that SAS was rated the No. 1 best place to work in the 2010 Fortune study and (2) announced that SAS achieved record revenues in 2009, despite the recession -- making it 34
Today is the 20th anniversary of JMP's first release, and I want to thank everyone who has helped to make JMP a success. JMP Version 1 shipped on October 5, 1989 -- or as we claimed at the time September 35 -- so that we could say we shipped in
