Imputes missing data according to a specified imputation strategy.

name = 'Simple Imputer'

Instance attributes

needs_fitting
parameters	Returns the parameters which were used to initialize the component

Methods:

__init__	Initalizes an transformer that imputes missing data according to the specified imputation strategy.”
clone	Constructs a new component with the same parameters
describe	Describe a component and its parameters
fit	Fits imputer to data. ‘None’ values are converted to np.nan before imputation and are
fit_transform	Fits on X and transforms X :param X: Data to fit and transform :type X: pd.DataFrame :param y: Labels to fit and transform :type y: pd.
load	Loads component at file path
save	Saves component at file path
transform	Transforms data X by imputing missing values. ‘None’ values are converted to np.nan before imputation and are
