METHODS AND APPARATUS TO EVALUATE MODEL STABILITY AND FIT

摘要

Methods, an apparatus, systems and articles of manufacturers for evaluating model stability and fit are disclosed. An example method disclosed in the present specification comprises: building a fit function based on causal factors associated with a marketing mix model; building a stability function based on override factors associated with corresponding ones of the causal factors; and integrating scaling factors into the stability function to facilitate a combined regression analysis of the fit function and the stability function, wherein the scaling factors are respectively associated with corresponding causal factors.
