Nested Modelling: If Model A is nested in Model B, then the parameters of Model A are a subset of the parameters of Model B.

In the case of a Nested Macro Econometric Model, any previous policy, investment plan, social regulation, ..etc which was applied previously would be nested out of the historical data and then the historical data of selected key economic indicators would be resolved again using the model. The difference between the actual data and the revised estimated historical data without the policy which was applied already would represent the historical impact on each of the variables.

SNMEM could be linked to any economic and/or social model which Advanced Analytics has built and also to any index such as the Gini and HDI. Its methodology is statistical and it would pertain economic theory while linking to the appropriate model to answer the question needed about the historical impact of the policy under study.
