I'm working with biological data. Almost all the input data have errors around 10 - 30% (or more) :-) Two correct decimals is more than my customers need. But other users do of course have other needs.
Can't remember where I saw it now, but I believe folks recomend at least 6 decimal digits precision in the stat software's calculation. I believe the problem with using lgamma is you can end up with no digits correct in some cases :-( John.
