Effect Leverage Step-by-Step

thaumaturgy — Sat, 26 Jun 2010 22:16:41 GMT

I am looking for a good "step-by-step" instruction on how JMP calculates and plots the Effect Leverage Plots for each individual effect in a given model.

Any recommendations?

Thanks,
-Chris

The Applied Statistical Essentials webcast from Predictum covered leverage plots.

See if the two leverage plot episodes give you what you need.

if you'd like, send me an email ( levin@predictum.com ) and I'll send you a script which walks you through the steps (it's shown on the videos that Jeff Perkinson referred to).

I love leverage plots - really awesome innovation.

Thanks! I'll take a look through the posted link!

I really like the leverage plots as well as a diagnostic, but when people ask me what they are I am having difficulty explaining it other than to say what the JMP manuals say I should use them to do.

wjlevin,
Was that your presentation on leverage plots? THAT. WAS. PERFECT!

That had to be the most perfectly crafted podcast for a stats topic I have ever seen. It had exactly the information I wanted and presented it clearly and succinctly!

THANK YOU!

The link by @Jeff_Perkinson below is not working. I appreciate it if the link to the webcast can be corrected.

Unfortunately it doesn’t seem to be available any more. Perhaps @wjlevin can find an archive.

I came across a recent request and uploaded the original videos to Vimeo.

The first video focusses on how to interpret leverage plots: https://vimeo.com/757403935/be20c9d066.

The second video takes you through a step-by-step in how they are put together to further aid in understanding them: https://vimeo.com/757403925/851d322e48

You’ll see reference to a script there - that is no longer available but it is incorporated in an Add-in. If you are interested in receiving the add-in, please send an email to info@predictum.com and ask for the Illustrations & Modeling aids add-in.
