I’m sure there is a more technically correct term for this: I use the phrase segmented regression to describe the process whereby I select a segment of data within a curve and build a regression model for just that segment.
I have some code to aid the process. The code illustrates how to perform regression on-the-fly as well as how to utilise the MouseTrap function to handle mouse movement events.

I often cross reference hotel booking sites with TripAdvisor, and its a laborious process.

JMP is brilliant for real-time data capture. Add to that the ability to use JSL to construct “industrial” style user-interfaces and its easy to get JMP deployed in an environment that relies on simple to use robust data capture from online measurement systems.
This is one of a series of posts highlighting new features available in version 13 of JMP.
