WebThe grand mean is (3+5+10)/3 = 6 (remember, the number of cases in each group mean doesn't matter as long as they're equal to one another). So the next step is to find the first set of "between group" squared means: (3-612 = 9 the next set is (5-6)2 = 1, and the third set is (10-6)2 = 16 (remember that squaring a negative number yields a ... WebMay 23, 2024 · To do so, you should subtract the individual-specific and time-specific means and add back the grand mean, as follows (suppose x i t is scalar without loss of generality): y i t = α i + θ t + β x i t + u i t y ¯ i := 1 T ∑ t = 1 T y i t = α i + θ ¯ + β x ¯ i + u ¯ i y ¯ t := 1 N ∑ i = 1 T y i t = α ¯ + θ t + β x ¯ t + u ¯ t
