Many analysts are too fascinated by instruments and methods for detoxification, modeling, and visualizing datasets and never involved sufficient with asking the best questions. during this functional consultant, information method advisor Max Shron exhibits you the way to place the why earlier than the how, via an often-overlooked set of analytical abilities.

Correspondingly, for another BSC V on the same X and Y we denote V (0 |1) = V (1 |0) = v1 , V (0 |0) = V (1 |1) = v2 . It is clear that w1 + w2 = 1, v1 + v2 = 1. The maximal value of the mutual information IP,V (X ∧ Y ) in the definition of Rsp (E, W ) is obtained when p∗ (0) = p∗ (1) = 1/2 because of symmetry of the channel, therefore IP ∗ ,V (X ∧ Y ) = 1 + v1 log v1 + v2 log v2 . The condition D(V W |P ∗ ) ≤ E will take the following form: v1 log v1 v2 + v2 log ≤ E. 15)) −(1 + v1 log v1 + v2 log v2 ) = max − v1 log wv11 + v2 log wv22 − E = 0 v1 + v2 = 1.
6, it repeats all steps of analogous demonstration for reliability function E(R, W ), made by Csisz´ar and K¨orner by the method of graph decomposition . 10) and Rx (E, W ) = max Rx (P, E, W ). 7. For DMC W for any E > 0 the following bound holds R(E, W ) ≥ max(Rr (E, W ), Rx (E, W )). In the next theorem the region, where the upper and the lower bounds coincide, is pointed out. Let Ecr (P, W ) = min E : ∂Rsp (P, E, W ) ≥ −1 . 8. For DMC W and PD P , for E ∈ [0, Ecr (P, W )] we have R(P, E, W ) = Rsp (P, E, W ) = Rr (P, E, W ), and, particularly, for E = 0 Rsp (P, 0, W ) = Rr (P, 0, W ) = IP,W (X ∧ Y ).
In other words Rsp (P, E, W ) − Rsp (P, E , W ) < −1, E−E when E < E ≤ Ecr , from where Rsp (P, E, W ) + E < Rsp (P, E , W ) + E , and consequently min E :E ≤E
