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) &...
