Sensitivity analysis
Explore how observations affect results
Compare an original model with carefully documented observation changes.
Compare before and after
See the original and filtered estimates side by side. Every deletion can be reviewed and undone.
How your data is stored
Unsaved uploads expire with your session. Saved projects remain until you delete them. Do not upload names or sensitive identifiers.
What diagnostic flags mean
Flags identify observations worth investigating. Remove an observation only when you can document a research reason.
