Well, the error ratio is something like the correctly correctly classified examples divided by the wrong ones or soemthing such. I know my packages are used, let's say by 5 peoples. but John reported nobody using it, so 5/0 -> inifity. > The error rate is the proportion misclassified, which cannot be > infinite under any circumstances where there are some subjects.

Ah, yes, that is the stuff taken in the other direction, but then, the error ratio in my example would be 0 (as 0 correct over 5 total). speaking of 0 error ratio doesn't seem reasonable. Maybe 100 % error ratio would be what we want here. Anyway, it is clear that the data provided by John were crap, and cannot be used. > There is probably a non-zero error, but I think it would need to be > greater than .5% before you can claim the table is showing the wrong > number. It shows 0, so if at least one person uses it (like me) then we already have 100% wrong values, no ? Friendly, Sven Luther
