Trait ndarray_stats::histogram::strategies::BinsBuildingStrategy [−][src]
A trait implemented by all strategies to build Bins
with parameters inferred from
observations.
This is required by GridBuilder
to know how to build a Grid
’s projections on the
coordinate axes.

Returns a strategy that has learnt the required parameter fo building Bins
for given
1-dimensional array, or an Err
if it is not possible to infer the required parameter
with the given data and specified strategy.
