Research:Metrics/edit rate

Rationale

This metric measures the number of contributions the editor does every day. This is a basic metric both for retention and editing volume. The edit count is a more widely used metric within the community, but it lacks the temporal dimension. Moreover, the way the edit rate changes over the tenure of an editor is a valuable information that can tell us in advance how that editor will perform in the future..

Pros/Cons

Pros:

• Easy to understand: average number of edit per day
• Amenable to data mining for predicting future performance of an editor

Cons:

• Does not convey any information about edit quality nor editing style
