java.lang.Object
  de.torstennahm.integrate.error.SimpleEstimator

All Implemented Interfaces:

ErrorEstimator

public class SimpleEstimator
extends java.lang.Object
implements ErrorEstimator

Provides a very simple estimate of the integration error. The estimate given is the absolute difference between the integral value at n/2 and n function evaluations, where n increases with new log entries.
