Hi jdfr,
From the top of my head I think the only thing they do not tell you in the guidance is that the sample data is already ln-tranformed.
You would need to combine some mean squares for MSB as variability between comes from different units and different batches. I do not readily have a recipe. I am sure it can be worked out pretty easily, but again why do it when the guidance has a perfect example with equations for it?
Xbarijk. is to be understood as:
The value of X for the i'th unit of the j'th batch for the k'th product averaged over the m stages of your data.
❝ Should one use log transformed data? In step 1 it says so, but when calculating ED from table in step 3, the final value comes from calculating using mean values from the untransformed variable.

❝ If I were to do an ANOVA to extract MSB and MSW, should I use a single effect of the containers or add any other effect to it? Doing so didn't lead me to achieve the same results as the ones found in the example.

❝ It might be easier that way, but I am having trouble in computing the numerator of both MSB and MSW. Any tip?
❝ Also, could you clarify "Xbar ijk is the average m life stages for ith bottle in batch # j", please?
