“…The free variables in the objective function are γ th , α and ρ p . However, α is obtained as per probability method in case of FFR [5], whereas it is fixed to two‐third in the case of SFR. Therefore the mean SE of FFR is given as where and However, as α = 2/3 in SFR, the mean SE of SFR in CB and EB is similar to (31) and (32), but the terms αβ and ((1 − α )/3) β in the equations become (2/3) β and (1/3) β .…”
