abstract = {Model reduction by the simplified Routh approximation method (SRAM) is extended to produce biased models. The method uses only one Routh-type array to generate both numerator and denominator of the kth-order model. Computation of the time moments and Markov parameters of the retained system beforehand and solving the Pad{\~A}{\copyright} equation for the reduced numerator are not necessary. Numerical examples illustrate the method.},
