WitrynaAll of the imputation parameters (variable_schema, mean_match_candidates, etc) will be carried over from the original ImputationKernel object. When mean matching, the candidate values are pulled from the original kernel dataset. To impute new data, the save_models parameter in ImputationKernel must be > 0. Witryna20 cze 2024 · A very powerful method on time series data with a datetime index, is the ability to resample() time series to another frequency (e.g., converting secondly data into 5-minutely data). The resample() method is similar to a groupby operation: it provides a time-based grouping, by using a string (e.g. M, 5H,…) that defines the target frequency
