1. A method for optimizing financial performance, the method comprising: receiving time series data, the time series data including data describing the financial performance generated by corresponding marketing investments made as a function of time; configuring an econometric model from the time series data, the econometric model including linear coefficients that define a quantitative linear relationship between the financial performance and the corresponding marketing investments; adjusting the linear coefficients in accordance with qualitative factors, thereby enabling the qualitative factors to be quantified into the econometric model; transforming the econometric model into an aggregated non-linear econometric model, the aggregated non-linear econometric model including non-linear factors that cause the financial performance to change at a varying rate as a function of the marketing investments; and adjusting an allocation of the marketing investments generated by the aggregated non-linear econometric model by applying an optimization algorithm to provide an optimized financial performance.
