Power Calculations

The next sections give formulas for computing the least significant number (LSN), least significant value (LSV), power, and adjusted power. With the exception of LSV, these computations are provided for each effect, and for a collection of user-specified contrasts (under Custom Test and LS Means Contrast). LSV is computed only for a single linear contrast. In the details below, the hypothesis refers to the collection of contrasts of interest.
