830574 - Normalize percentages

Status: RESOLVED FIXED

Description

[Steve Fink [:sfink] [:s:]]

In a crash reports page, eg https://crash-stats.mozilla.com/report/list?signature=js%3A%3Agc%3A%3AScanRope it tells me things like "99.729% of these crashes occur on x86, only 0.271% on amd64." If I wanted to know if the problem is specific to (or at least highly correlated with) 32-bit, this information is not helpful without also knowing what percentage of crash report submitters are on x86 vs amd64.

I would like all the percentages on that page to be listed both ways, as a raw percentage of reports and normalized by relative proportions of submitters. (The raw percentage is still mildly useful since it gives an estimate of what percentage of our user base is affected. Though if there only one percentage displayed, I'd much rather see the normalized one.)

I most often want this for Firefox versions, since otherwise it always looks like there's a sharp dropoff shortly after a new version is released.

dbaron's correlation report does this normalization and is enormously helpful, but it only covers the ones that it runs for, and it displays a bunch more information that doesn't really fit on the at-a-glance page.

The report list is deprecated but you can achieve the normalized result using SuperSearch.
