Why do I get a warning that outlier statistics and limits have changed when importing old models?Report
Because the outlier detection and reporting have undergone changes since earlier versions, the Outlier Warnings and Outlier List nodes have become obsolete since version 10.4. Whenever a model containing these nodes is opened or imported, these nodes will be deleted from the models with a warning.
Recalculating the models is recommended to benefit from the current outlier detection and reporting functionality.
If it is important to retain the old models without change for future reference, care must be taken to save the project file with a different name.
