The NaN values should be stripped before calling these Median_high(), median_grouped(), mode(), multimode(), and The functions affected are median(), median_low(), Undefined behaviors in the statistics functions that sort data or that count Since NaNs have unusual comparison semantics, they cause surprising or Some datasets use NaN (not a number) values to represent missing data. You may be able to use map() to ensure a consistent result, for If your input data consists of mixed types, Collections with a mix of types are also undefinedĪnd implementation-dependent.
