Method Summary
`boolean`	`equals(Object object)` Returns true iff `object` is a `StatisticalSummaryValues` instance and all statistics have the same values as this.
`double`	`getMax()` Returns the maximum of the available values
`double`	`getMean()` Returns the arithmetic mean of the available values
`double`	`getMin()` Returns the minimum of the available values
`long`	`getN()` Returns the number of available values
`double`	`getStandardDeviation()` Returns the standard deviation of the available values.
`double`	`getSum()` Returns the sum of the values that have been added to Univariate.
`double`	`getVariance()` Returns the variance of the available values.
`int`	`hashCode()` Returns hash code based on values of statistics
