Binning (p.prbnmcn-stats.0.0.7.doc.prbnmcn-stats.Stats.Binning)

Sourcetype spec

The type of binning specifications (shape of the grid, etc)

val regular : 
  origin:float ->
  width:float ->
  truncate:(float * float) option ->
  spec

regular ~origin ~width ~truncate specifies a regular grid with cells aligned on origin and spaced by width. Cells are indexed, with the cell [origin, origin+width] having index 0. If truncate is equal to Some (l, r), the points outside of the (inclusive) [l, r] interval will be discarded.

raises Invalid_argument
if width <= 0 or if truncate = Some (l, r)and the [l, r] interval is empty.

Sourceval from_measure : spec -> float Fin.Float.mes -> int Fin.Float.mes

from_measure spec mes bins the mesure on the grid specified by spec. After binning, the measure is supported by cell indices corresponding to the specification.

Sourceval from_empirical : spec -> float Emp.t -> int Fin.Float.mes

from_empirical spec arr bins the array on the grid specified by spec. After binning, the measure is supported by cell indices corresponding to the specification.

Sourceval map_to_bin : spec -> float -> int option

map_to_bin spec x maps x to its cell as specified by spec. Returns None if the point is out of the range of spec.

Sourceval map_from_bin : spec -> int -> float option

map_from_bin spec i maps the cell index i to the starting position of its cell.

Returns None if the index is out of the range of spec.
