Algorithm Calculates Cumulative Poisson Distribution
Author and Affiliation:
Bowerman, Paul N.(Caltech)
Nolty, Robert C.(Caltech)
Scheuer, Ernest M.(Caltech)
Abstract: Algorithm calculates accurate values of cumulative Poisson distribution under conditions where other algorithms fail because numbers are so small (underflow) or so large (overflow) that computer cannot process them. Factors inserted temporarily to prevent underflow and overflow. Implemented in CUMPOIS computer program described in "Cumulative Poisson Distribution Program" (NPO-17714).
