ANOVA by items

Dear all :-) Suppose i have a factorial design with two between-subject factors (one factor A of 3 levels and one factor B of 2 levels) en two within-subject factors (one factor C of 2 levels and one factor D of 5 levels). Of course, to perform an ANOVA on this data, my matrix should like :

Confidence Intervals for Estimates of Effect Sizes

A week or so ago I suggested the following: Some of those who think that estimation of the size of effects is more important than the testing of a nil hypothesis of no effect argue that we would be better served by reporting a confidence interval for the size of the effect. Such confidence

false positives when testing for anthrax

I caught part of a news story on TV saying that an office that had tested positive for anthrax was pronounced clean after further testing. Does anyone have any numbers on the probability of a false positive when using the test for anthrax? This info would be useful since I am just now talking
