Usefulness of the modified partial differences method in complex ratio analysis

Summary/Abstract: The aim of the paper is presentation of the theory behind the partial differences method and evaluation of its usefulness in contemporary, complex ratio analysis. The Taylor-series-based analysis facilitates calcu-lation in cases of complexity of the analyzed function and considerable number of explanatory variables; furthermore, the existence of the remainder term is the premise to ignore next terms of the Taylors series, which represent common differences. Such a step eliminates the problem of their sometimes embarrass-ing interpretation. An example of the efficient analysis of RIOA, i.e. the modified residual income to total assets ratio is presented. The system of the RIOA consists of nine factors.
