An earlier article [1] presented two formulas for approximating the upper binomial confidence limit p̄ from a sample of size n with c "defectives" drawn randomly from an infinite population with ...
An approximation for negative binomial sums involving a minimum of arithmetic is presented. Because of the relationship between negative binomial sums and regular binomial sums the approximation can ...
A heuristic algorithm that accurately and quickly approximates loss distributions for portfolios of independent credits is introduced in this paper. An algorithm such as this can be used in the ...
