  1. In the last two rows the fitted values for \(T_\text {Interval}/{b_a}\) and \(T_\text {Interval}/{b_d}\) were multiplied with the factors from row 1 and 3 respectively to obtain estimates for \(T_\text {Interval}/{b_c}\). See List of symbols at the begining of the article for an explanation of the parameters.
