NCIN Outlier Advisory Group

Where it is not clear whether outlier handling is required, the work should be flagged with the NCIN's Outlier Advisory Group by emailing outliers at ncin dot link with a description of the planned analysis and a recommendation for whether outlier handling should be applied. The group will consider whether outlier handling is required and respond to confirm this.

A list of previous decisions by the group is available for reference. Analyses very similar to those that have already been considered should follow the established precedent.


To provide advice where it is uncertain whether outlier handling processes should be implemented for specific analytical projects. Initially this group will review all analyses from within NCIN that may require outlier handling under NCIN's guidance on this subject. As a body of precedent is established, the number of projects that require advice from this group is likely to reduce.


To be announced.
