> I would be great if this feature supported Standard Deviation to do some
simple statistics.
I've just updated the github repository with StdDev and Variance,
including an optional flag to do sample stats instead of population stats.
Be warned, however: SQlite doesn't provide these aggregates out of the box
- you will need to install an SQLite extension module to get StdDev and
Variance.
