static SemiVariance.Direction | 
SemiVariance.DOWNSIDE_VARIANCE
The DOWNSIDE Direction is used to specify that the observations below
 the cutoff point will be used to calculate SemiVariance 
 | 
static SemiVariance.Direction | 
SemiVariance.UPSIDE_VARIANCE
The UPSIDE Direction is used to specify that the observations above the
 cutoff point will be used to calculate SemiVariance.

|---|---|
double | 
SemiVariance.evaluate(double[] values,
        double cutoff,
        SemiVariance.Direction direction)
Returns the  
SemiVariance of the designated values against the cutoff in the
 given direction, using the current value of the biasCorrection instance property. | 
double | 
SemiVariance.evaluate(double[] values,
        double cutoff,
        SemiVariance.Direction direction,
        boolean corrected,
        int start,
        int length)
Returns the  
SemiVariance of the designated values against the cutoff
 in the given direction with the provided bias correction. | 
double | 
SemiVariance.evaluate(double[] values,
        SemiVariance.Direction direction)
This method calculates  
SemiVariance for the entire array against the mean,
 using the current value of the biasCorrection instance property. | 
SemiVariance | 
SemiVariance.withVarianceDirection(SemiVariance.Direction direction)
Returns a copy of this instance with the given direction setting.
