¥ Null Hypothesis: H0 : m1 = m2 = É = mr
H i.e. drug
dose has no effect
HAlternative Hypothesis: Ha: not all m are equal
H i.e. at least one drug dose had an effect
HNOTE: 3dANOVA only allows
fixed effect modeling. This means that the inferences about drug dose effect are limited to the
doses tested. Effectively, this is a generalization of t-test to
multiple columns of data.
