Regression Residuals - Dashboard

When we perform a regression (simple, multiple, DOE,...) one key activity (for the model check) is the evaluation of the residuals.

Typically, the residual evaluation consist in 4 key checks:

1) Normality of the residuals distribution (with the distribution and p-value evaluation);

2) Randomly distributed (typically we use a chart with residuals versus the fitted values);

3) No residuals trend (typically we use a chart with residuals versus the order of the data);

4) Standardized residuals between -2 and +2.

 

JMP can manage this kind of residuals... but in different menu and in some case not so user-friendly.

One improvement opportunity: create a button "Residuals Check" -> when the user click on it -> JMP generate one single screen (one page dashboard) with 4 quadrants that reppresent the 4 different residuals check.

In this way... this is more easy for not expert users and very fast verification in one click.

Thanks in advance for your attention and feedback.

Best Regards,

Simone
