[Further study on the indices of the power of an effect]

The correlations binding the indices of influence power factor in the analysis of variance by functional dependence are given. These indices are calculated by means of Plokhinskiĭ's, Mills-Lukomskiĭ's and Snedekor's methods. The domains of maximum effectiveness of each index depending on the structure of variance complexes are determined. The conditions of equivalence of all indices of influence power are found.
