Authors: J.J. Hernandez, S. Navas
Program title: JASP
Catalogue identifier: ADES_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 100(1997)119
Programming language: Fortran.
Computer: ALPHA 200 4/233.
Operating system: DEC OSF/1 V3.2A, OpenVMS V6.0, IBM VM/ESA Rel 2.
RAM: 100K words
Word size: 32
Keywords: General purpose, Quadrature, Statistics, Discovery, Exclusion, Limits, Search.
Classification: 4.11.

Nature of problem:
Estimation of discovery and exclusion limits in prospective studies using Poisson statistics and properly including the experimental fluctuations.

Solution method:
Iterative process using the relation between the sums of terms of the Poisson series and the chi-square distribution.

Restrictions:
For certain values, e.g., when the signal and background are very close, the procedure may not converge.

Unusual features:
CERN Program Library required.

Running time:
A few milliseconds per estimate in an ALPHA 200 4/233.
