Release date: 2023-04-12
Remove type validation for some period columns as they are only used for data grouping.
In line with the changes in the previous release, the period columns in some methods are also only present for grouping purposes and thus checking their data types in the input schema is unnecessary. This release removes these checks.
This change applies to the column referenced by the period_col parameter
in the HT Ratio Estimation and Winsorisation methods. This column is still
checked in Imputation since this method relies on the format of the period
to perform calculations.
This release does not have any impact on method outputs produced by existing code.
