multiple comparisons in nested design
...gues I need to perform a analysis of dates from a nested experimental design. From "Bioestatical Analysis" of Zar "Bimetry of Sokal" & Rohlf "Design and Analysis of Experiments" of Montgomery I have: Sum (mean(x)_i - mean(x)_T)2 / (a-1) -> var(epsilon) + n sigma2_B + n b (sum alfa_i)2 / (a-1) Sum (mean(x)_ij - mean(x)_i)2 / (ba-a) -> var(epsilon) + n sigma2_B Sum (x_ijl - mean(x)_ij)2 / (abn-ab) -> var(epsilon) Dates for the execution of a example: #> Mesures <- as.data.frame(matrix(rnorm(45*1, mean=10, sd=1), ncol=1)) #> colnames(Mesures) &...
