- class DropNA(axis=0, how=None, thresh=None, remember=None)[source]#
Drop missing values transformation.
Drops rows or columns with missing values from X. Mostly wrapspandas.DataFrame.dropna, but allows specifying thresh as a fraction ofnon-missing observations.
- Parameters:
- axis{0 or ‘index’, 1 or ‘columns’}, default 0
Determine if rows or columns which contain missing values are removed.Must be 0 or ‘index’ for univariate input.
0, or ‘index’ : Drop rows which contain missing values.
1, or ‘columns’ : Drop columns which contain missing value.
- how{‘any’, ‘all’}, default ‘any’
Determine if row or column is removed from DataFrame, when we haveat least one NA or all NA.
‘any’ : If any NA values are present, drop that row or column.
‘all’ : If all values are NA, drop that row or column.
- threshint or float, optional
If int, require at least that many non-NA values (as in pandas.dropna).If float, minimum share of non-NA values for rows/columns to beretained. Fraction must be contained within (0,1]. Setting fractionto 1.0 is equivalent to setting how=’any’. thresh cannot be combinedwith how.
- rememberbool, default False if axis==0, True if axis==1
If True, drops the same rows/columns in transform as in fit. If false,drops rows/columns according to the NAs seen in transform (equivalentto PandasTransformAdaptor(method=”dropna”)).
