#30056: Add SQLite support for StdDev() and Variance() -------------------------------------+------------------------------------- Reporter: Nick Pope | Owner: nobody Type: New | Status: new feature | Component: Database | Version: 2.1 layer (models, ORM) | Keywords: sqlite, stddev, Severity: Normal | variance, statistics Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- `StdDev()` and `Variance()` are currently supported for SpatiaLite, but not SQLite. Django's documentation highlights that there is an extension module available that provides support, but there are problems with this suggestion:
- This extension module is not provided compiled and only implements `STDDEV` and `VARIANCE`. - Django uses `STDDEV_POP` and `STDDEV_SAMP` for `StdDev()`; `VAR_POP` and `VAR_SAMP` for `Variance()` - so they wouldn't work anyway. As an alternative, we can make use of the `statistics` module added to the standard library in Python 3.4. -- Ticket URL: <https://code.djangoproject.com/ticket/30056> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
