<p>Methods, apparatus, systems and articles of manufacture are disclosed to evaluate model stability and fit. An example method disclosed herein includes 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, the scaling factors respectively associated with corresponding causal factors.</p> |
