Integrated Poisson probability

This function returns the probability that an integer random variable which obeys a Poisson distribution about an average `av' will EQUAL OR EXCEED `i'.

  real(single) function integratedPoissonProb(av, i)
    real(single), intent(in) :: av
    integer, intent(in) :: i
  end function integratedPoissonProb
