Proc mixed mean square error
Webb11 juli 2014 · 1 Answer. You should use the SSQ function to calculate sum of squares in IML. Here are several other ways to do this. Note the first way gives a different result (as it's summing the squares of s and -t), just an example of the difference of how you pass the arguments. proc iml; x = 1:5; y = j (1,5,2); e1=ssq (x,-y); *sum of the squares, not ...

WebbANOVA. These computations are shown in this paper in next examples. As usual, the mean squares (MS) are found by dividing the sums of squares(SS) By the corresponding degrees of freedom. Variation from patient-to-patient is one type of random error, as estimated by the mean square for Patient (within Group). If
