The publisher apologises for a typographical error introduced during production in Equation 1. The correct specification of Equation 1 (as submitted and accepted) is:
$${E\left( {{S_i} = 1} \right) \!= \!\left[ {\left\{ {{{\mathop \sum \nolimits_{i = 1}^n Y_i^{ListA}{T_i}} \over {\mathop \sum \nolimits_{i = 1}^n {T_i}}} - {{\mathop \sum \nolimits_{i = 1}^n Y_i^{ListA}\left( {1 - {T_i}} \right)} \over {\mathop \sum \nolimits_{i = 1}^n \left( {1 - {T_i}} \right)}}} \right\} \!+ \!\left\{ {{{\mathop \sum \nolimits_{i = 1}^n Y_i^{ListB}\left( {1 - {T_i}} \right)} \over {\mathop \sum \nolimits_{i = 1}^n \left( {1 - {T_i}} \right)}} - {{\mathop \sum \nolimits_{i = 1}^n Y_i^{ListB}{T_i}} \over {\mathop \sum \nolimits_{i = 1}^n {T_i}}}} \right\}} \right]/2}$$
