Method Summary

void	addValue(double value, double weight) Adds a value to the interval estimator.
double[][]	predictIntervals(double confidenceValue) Returns the intervals at the given confidence value.

Method Detail

addValue

void addValue(double value,
              double weight)

Adds a value to the interval estimator.

Parameters:

value - the value to add

weight - the weight of the value

predictIntervals

double[][] predictIntervals(double confidenceValue)

Returns the intervals at the given confidence value. Each row has one interval. The first element in each row is the lower bound, the second element the upper one.

Parameters:

confidenceValue - the value at which to evaluate

Returns:

the interval
