- Method Detail
  - getStatistic
```
public double getStatistic()
```
    Returns the test statistic.
    This is the U₁ statistic. Compute the U₂ statistic using the original sample lengths n and m using:
    u2 = (long) n * m - u1;
    Specified by:
    
    getStatistic in interface SignificanceResult
    
    Returns:
    
    the statistic
  - hasTiedValues
```
public boolean hasTiedValues()
```
    Return true if the data had tied values.
    Note: The exact computation cannot be used when there are tied values.
    
    Returns:
    
    true if there were tied values
  - getPValue
```
public double getPValue()
```
    Description copied from interface: SignificanceResult
    
    Returns the test statistic p-value.
    The number returned is the smallest significance level at which one can reject the null hypothesis.
    
    Specified by:
    
    getPValue in interface SignificanceResult
    
    Returns:
    
    the p-value
