Linear Statistical Models
Expected Means Squares Further Revealed
The truth is that I simplified expected mean squares so that we could focus on making correctly
The fact of the matter is, that the notation for expected means squares changes depending upon
whether a variable is a fixed variable or whether it is a random variable.
The notational system that was used, so far, in class is correct for random variables but not for
Fixed variables use the treatment effect squared divided by degrees of freedom.
