Robust Estimators are Hard to Compute
Bernholt, Thorsten - 2006
In modern statistics, the robust estimation of parameters of a regression hyperplane is a central problem. Robustness means that the estimation is not or only slightly affected by outliers in the data. In this paper, it is shown that the following robust estimators are hard to compute: LMS, LQS,...

On the initialization of adaptive learning in macroeconomic models
Berardi, Michele; Galimberti, Jaqueson K. - 2016
We review and evaluate methods previously adopted in the applied literature of adaptive learning in order to initialize agents' beliefs. Previous methods are classified into three broad classes: equilibrium-related, training sample-based, and estimation-based. We conduct several simulations...
