Perform survival analysis on user satisfaction data
Closed, ResolvedPublic4 Story Points


Okay, (the collective) we designed a schema, implemented it, and started collecting the data. Initial looks into it suggest the schema is valid -- in other words, doesn't introduce a sampling bias. If that is the case, we need to analyze the session lengths that we're logging. Perform standard survival analysis on the checkins in the TestSearchUserSatisfaction2 schema.

Coming soon after I get some rest: the answer to the question "Do enwiki users stay on pages longer than users on other wikis?" *dramatic music*


  1. We probably want to dig in more what the old and new EL schemas do and did.
  2. "and then later we would use statistical methodology for dealing with right-censored data." I don't know what this means, and I work here ;p.
  3. "bug (introduced on September 10th, 2015) in the Event Logging (EL) system" is all link. Shorter link?
  4. "whether were differences" - "whether there were differences"
  5. There's kind of a lot of TLAs in this. Could we define terms and then either use the full names or the abbreviations but not both?

Everything else looks good!
