What does this implement/fix? Explain your changes.
Enabling the possibility to specify multiple
missing_valuesin SimpleImputer, as discussed in this issue: #17625PR still in progress to be discussed in the issue.
Any other comments?
The idea is to start by allowing multiple missing values and then, in a later PR, change the default
missing_valuesto include all common missing values (np.nan,None,pd.NA,pd.NaT). There may be an intermediate PR after this one, before the later PR that changes the default, to add a FutureWarning explaining the upcoming change in the defaultmissing_values.
