SUM(W2) | The sum of squared weights. Shown as in the formulae. |
EFFBA | The effective base. Shown as ek in the formulae. |
SUM(W) | The sum of weights for overlapping data in column A, shown as wo in the formulae. |
SUM(WX1) | The sum of (weights times factors) for overlapping data in column A. Factors are 1.0 for all tests except the test on column means. |
SUM(WX12) | The (sum of (weights times factors)) squared for overlapping data in column A. Factors are 1.0 for all tests except the test on column means. |
