Crate classif [−] [src]
Library for one-dimensional data classification and simple statistics, especially methods used for cartographic purposes such as "quantiles breaks" or "Jenks natural breaks".
This library allows to computed break values according to a few methods (listed in
the Classification
Enum).
Theses break values can be computed by creating a new BoundsInfo
struct.
If the input values are already sorted and you don't care about error checking
you can directly use the get_{jenks|quantiles|etc...}_breaks
functions.
This library also provide a few basic statistical functionnalities, allowing to compute mean value, kurtosis value, standard deviation, variance, root of mean square, etc.
Modules
stats |
Basic statistical functionnalities: mean, standard deviation, kurtosis, variance, etc. |
Structs
BoundsInfo |
A struct containing the bounds computed at its creation and some basic statistical informations : minimum, maximum and mean value. |
Enums
Classification |
The various type of classification methods availables. |
Functions
get_arithmetic_breaks |
Compute the "arithmetic progression" breaks on a list of sorted values. |
get_equal_interval |
Compute the equal interval breaks on a list of sorted values. |
get_head_tail_breaks |
Compute the "Head-Tail" breaks on a list of sorted values (to be used on heavily right skewed distributions). |
get_jenks_breaks |
Compute the "Natural Breaks" on a list of sorted values, based on Jenks optimization. |
get_quantiles |
Compute the quantiles breaks on a list of sorted values. |
get_tail_head_breaks |
Compute the "Tail-Head" breaks on a list of sorted values (its actually just the inverse of the Head-Tail method, to be used on heavily left skewed distributions). |
