High-dimensional data bootstrap
WebBagging, also known as bootstrap aggregation, is the ensemble learning method that is commonly used to reduce variance within a noisy dataset. In bagging, a random sample of data in a training set is selected with replacement—meaning that the individual data points can be chosen more than once. After several data samples are generated, these ... Webhigh dimensional systems. By data based or "parametric bootstrap" Monte Carlo simulations, we mean simulations where the Data Generating Process (DGP) uses the parame-ter values obtained from an estimation using actual data. We base our simulations on estimated parameter values in order to ascertain that our results are empirically …
