public SingletonStatistics(double value)

Method Detail

getMax

public double getMax()

Description copied from interface: Statistics

Returns the maximum for this statistics.

Returns:

maximum

getMin

public double getMin()

Description copied from interface: Statistics

Returns the minimum for this statistics.

Returns:

minimum

getN

public long getN()

Description copied from interface: Statistics

Returns the number of samples in this statistics.

Returns:

number of samples

getSum

public double getSum()

Description copied from interface: Statistics

Returns the sum of samples in this statistics.

Returns:

sum

getPercentile

public double getPercentile(double rank)

Description copied from interface: Statistics

Returns the percentile at given rank.

Parameters:

rank - the rank, [0..100]

Returns:

percentile

getVariance

public double getVariance()

Description copied from interface: Statistics

Returns the variance for this statistics.

Returns:

variance

getHistogram

public int[] getHistogram(double[] levels)

Description copied from interface: Statistics

Returns the histogram for this statistics. The histogram bin count would be equal to number of levels, minus one; so that each i-th bin is the number of samples in [i-th, (i+1)-th) levels.

Parameters:

levels - levels

Returns:

histogram data

getRawData

public Iterator<Map.Entry<Double,Long>> getRawData()

Description copied from interface: Statistics

Returns the raw data for this statistics. This data can be useful for custom postprocessing and statistics computations. Note, that values of multiple calls may not be unique. Ordering of the values is not specified.

Returns:

iterator to raw data. Each item is pair of actual value and number of occurrences of this value.
