WebSingle Index Model and Portfolio Theory Idea: Use estimated SI model covariance matrix instead of sample covariance matrix in forming minimum variance portfolios: min x0Σˆx … WebA single index model (SIM) summarizes the effects of the explanatory variables X 1, ..., X d within a single variable called the index. As stated at the beginning of Part II, the SIM is one possibility for generalizing the GLM or for restricting the multidimensional regression E(Y X) to overcome the curse of dimensionality and the lack of interpretability.
