`stats`

Statistical estimation shared by the marks that draw an estimate with its uncertainty – the start of the family #350 and #352 describe.

Everything here is a pure function over lists, tested against hand-computed values away from any rendering, so a chart only has to show that the numbers reached the glyph.

Structs

Estimator: What a group of observations is reduced to. Pass one to barplot().
ErrorBar: How the uncertainty around an estimate is sized.
SmoothMethod: Which curve Plot.annotate_smooth() fits (#147).
