  - aggregate
```
void aggregate(T other)
        throws NullArgumentException
```
    Aggregates the provided instance into this instance.
    This method can be used to combine statistics computed over partitions or subsamples - i.e., the value of this instance after this operation should be the same as if a single statistic would have been applied over the combined dataset.
    
    Parameters:
    
    other - the instance to aggregate into this instance
    
    Throws:
    
    NullArgumentException - if the input is null
  - aggregate
```
default void aggregate(T... others)
```
    Aggregates the results from the provided instances into this instance.
    This method can be used to combine statistics computed over partitions or subsamples - i.e., the value of this instance after this operation should be the same as if a single statistic would have been applied over the combined dataset.
    
    Parameters:
    
    others - the other instances to aggregate into this instance
    
    Throws:
    
    NullArgumentException - if either others or any instance is null
  - aggregate
```
default void aggregate(Iterable<T> others)

    This method can be used to combine statistics computed over partitions or subsamples - i.e., the value of this instance after this operation should be the same as if a single statistic would have been applied over the combined dataset.
    
    Parameters:
    
    others - the other instances to aggregate into this instance
    
    Throws:
    
    NullArgumentException - if either others or any instance is null
