SeriesModulegroupByK, T, TNewKey Method
Groups a series (ordered or unordered) using the specified key selector (`keySelector`) and then returns a series of (nested) series as the result. The outer series is indexed by the newly produced keys, the nested series are indexed with the original keys. ## Parameters - `keySelector` - Generates a new key that is used for aggregation, based on the original key and value. The new key must support equality testing. - `series` - An input series to be grouped. [category:Grouping, windowing and chunking]
