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,

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.

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!

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.
