All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description

- Method Detail
  - ingest
```
double ingest(double value)
```
    Ingest one value with weight 1. Should be called only from the Tally object and AFTER processing the value in the tally.
    
    Parameters:
    
    value - double; the value
    
    Returns:
    
    double; the ingested value
    
    Throws:
    
    IllegalArgumentException - when the ingested value is NaN
  - getQuantile
```
double getQuantile(Tally tally,
                   double probability)
```
    Compute (or approximate) the value that corresponds to the given fraction (percentile).
    
    Parameters:
    
    tally - Tally; the tally object that accumulates mean, minimum, maximum, count, etc.
    
    probability - double; value between 0.0 and 1.0 (both inclusive)
    
    Returns:
    
    double; the computed or approximated quantile value
    
    Throws:
    
    IllegalArgumentException - when the probability is less than 0 or larger than 1
    
    NullPointerException - when tally is null
  - initialize
```
void initialize()
```
    Reset (clear all accumulated information).
