addValue
public void addValue(double d) -
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
-
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
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.
-
getVariance
public double getVariance()Description copied from interface:Statistics
Returns the variance for this statistics.- Returns:
- variance
