ehrapy.preprocessing.winsorize#
- ehrapy.preprocessing.winsorize(adata, vars=None, obs_cols=None, limits=None, copy=False, **kwargs)[source]#
Returns a Winsorized version of the input array.
The implementation is based on https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.mstats.winsorize.html
- Parameters:
adata (
AnnData
) – AnnData object to winsorizevars (
str
|list
[str
] |set
[str
]) – The features to winsorize.obs_cols (
str
|list
[str
] |set
[str
]) – Columns in obs with features to winsorize.limits (
list
[float
]) – Tuple of the percentages to cut on each side of the array as floats between 0. and 1. Defaults to (0.01, 0.99)copy (
bool
) – Whether to return a copy or not**kwargs – Keywords arguments get passed to scipy.stats.mstats.winsorize
- Return type:
- Returns:
Winsorized AnnData object if copy is True.
