There are a lot of undefined metrics in your methods. For example, what do
you mean by "canonical definition of edit sessions". Is it [0]? Also, is
there something that we learn from this longevity analysis that we didn't
learn from previous research? E.g. [1] and [2]. One point that I think
would look into is the engagement measure used in [1] (# of edits in first
session after registration). In my work on [1], it looked like this stat
remained consistent since 2004 and therefor didn't seem to explain the drop
in newcomer retention.

Hi All,
I been working on graphs to visualize the entire edit activity of in wiki
for some time now. I'm documenting all of it at
https://meta.wikimedia.org/wiki/Research:Editor_Behaviour_Analysis_%26_Grap…
.
The graphs can be viewed at
https://cosmiclattes.github.io/wikigraphs/data/wikis.html. Currently only
graphs for 'en' have been put up, I'll add the graphs for the wikis soon.
Methodology
- The editors are split into groups based on the month in which they
made their first edit.
- The active edit sessions (value or percentage etc) for the groups
are then plotted as stacked bars or as a matrix. I've used the canonical
definition of an active edit session. The value are + or - .1% of the
values on
https://stats.wikimedia.org/
Selector
- There is a selector on each graph that lets you filter the data in
the graph. On moving the cursor to the left end of the selector you will
get a resize cursor. The selection can then are moved or redrawn.
- In graphs 1,2 the selector filters by percentage.
- In graphs 3,4,5 the selector filters by the age of the cohort.
Preliminary Finding
- Longevity of editors fell drastically starting Jan 06 and has since
stabilized at levels from Jan 07.

Would you to hear what you guys think of the graphs & any ideas you would
have for me.
