- All Implemented Interfaces:
- BinError
public class PoissonBinError
- extends java.lang.Object
- implements BinError
This class calculates the error on the bin assuming a Poisson distribution.
The error is calculated using the approximation ~ 1 + sqrt( h + 0.75 ) where
h is the height of the bin.
