I don't know if this fix breaks anything elseThe Normal estimate is crucial not only for the Normal quantile. A problem with small probabilities would cause inaccurate results with the Normal quantile as well  which I have not noticed yet. The Normal estimate distinguishes between two cases: 0,5 >= p > 0,23 and p < 0,23. So an error with small probabilities would affect every p < 0,23. That's why I wonder what exactly the problem was. Could you post the Normal estimate code before and after your last correction? Dieter
