gstools.transform.normal_to_arcsin
- gstools.transform.normal_to_arcsin(fld, a=None, b=None, field='field', store=True, process=False, keep_mean=True)[source]
Transform normal distribution to the bimodal arcsin distribution.
See: https://en.wikipedia.org/wiki/Arcsine_distribution
After this transformation, the field is arcsin-distributed on [a, b].
- Parameters
fld (
Field
) – Field class containing a generated field.a (
float
, optional) – Parameter a of the arcsin distribution (lower bound). Default: keep mean and varianceb (
float
, optional) – Parameter b of the arcsin distribution (upper bound). Default: keep mean and variancefield (
str
, optional) – Name of field to be transformed. The default is “field”.store (
str
orbool
, optional) – Whether to store field inplace (True/False) or under a given name. The default is True.process (
bool
, optional) – Whether to process in/out fields with trend, normalizer and mean of given Field instance. The default is False.keep_mean (
bool
, optional) – Whether to keep the mean of the field if process=True. The default is True.
- Returns
Transformed field.
- Return type
