Abstract:Least squares model averaging has been explored in depth from the theoretical perspective and has been used widely in empirical applications. In this talk, I will introduce least squares model averaging and its asymptotic optimality, weight convergence, asymptotic distribution and finite sample property. Also, I will talk about its extension to high-dimensional case and averaging machine learning methods.
