MeanAndStandardDeviation
public MeanAndStandardDeviation(Number mean,
Number standardDeviation)
Creates a new mean and standard deviation record.
mean
- the mean (null
permitted).standardDeviation
- the standard deviation (null
permitted.
MeanAndStandardDeviation
public MeanAndStandardDeviation(double mean,
double standardDeviation)
Creates a new mean and standard deviation record.
mean
- the mean.standardDeviation
- the standard deviation.
equals
public boolean equals(Object obj)
Tests this instance for equality with an arbitrary object.
obj
- the object (null
permitted).
getMean
public Number getMean()
Returns the mean.
getMeanValue
public double getMeanValue()
Returns the mean as a double primitive. If the underlying mean is
null
, this method will return Double.NaN
.
getStandardDeviationValue
public double getStandardDeviationValue()
Returns the standard deviation as a double primitive. If the underlying
standard deviation is null
, this method will return
Double.NaN
.
toString
public String toString()
Returns a string representing this instance.
