@ Aaron
- I've added the definitions. https://meta.wikimedia.org/wiki/Research:Editor_Behaviour_Analysis_%26_Graphs#Definitions.I'm using the historical definition - https://meta.wikimedia.org/wiki/Research:Refining_the_definition_of_monthly_active_editors#Historical_definition for an active editor.
- The longevity graph shows some interesting results when we compare 'en' with other languages like 'es', 'zh' etc. I'll upload them and send the link as soon as I can.
- Graphs 4&5 do show results that are different from [1]
- Graph 4 - Monthly Editor Activity Split By Cohort - Stacked Bars . Selecting 1-2 in the selector show the contribution of the cohort that joined in that month in all the months.
- Graph 5 - Monthly Editor Activity % Split By Cohort - Stacked Bars. Selecting the same (1-2 in the selector) show the contribution of the cohort that joined in that month as a % of the total activity in a given month for all months.
- In the month of Jan 07 , The cohort Jan 07 contributed 'x'%.
- The activity in month Jan 07 = cohort Jan 07 + cohort Dec 06 ..... Cohort Jan 01.
- The editor activity peaks in Jan 07 - March 07 as shown in Graph 4 and many other graphs [1] etc.
- Graph 5 show that for the same period the contribution in % for the cohorts joining in the months Jan 07 - March 07, aka the new comers each month has remained the same and it is < 40 %. So the older editors contributed 60+ % in those months. Which tell us that the contribution to the fall in active editors lies both with the new editors in a month and also the older editors. In fact the older editors contributed more to the fall.
- I have not looked specifically at (No of edits in first session after registration)
- It was [1] that got me working on the graphs :-)
