LinearScale

class

class LinearScale(
    min_val: ScaleLimitSpec,
    max_val: ScaleLimitSpec,
    bins: BinCountSpec = MAX_BINS,
    use_bin_zero: bool = False,
)

Bases: Scale

Categories: dq-classifier

A scale that splits [min_val, max_val] into equal-width bins (used with ScaleCategorizer).

Examples

Ten equally wide bins between 0 and 100:

ScaleCategorizer(["amount"], scale=LinearScale(0.0, 100.0, bins=10))

Parameters

parameter

min_valScaleLimitSpec (StrictInt | StrictFloat)

Lowest value of the scale; an int or float.

parameter

max_valScaleLimitSpec (StrictInt | StrictFloat)

Highest value of the scale; strictly greater than min_val.

parameter

binsBinCountSpec (StrictInt)

Number of bins to split the range into; a whole number from 1 to 100 (default 100).

parameter

use_bin_zerobool

If False, the minimum value belongs to the first bin; if True, min_val gets its own bin 0.
