Webb11 aug. 2024 · Over the past two decades, the Bootstrap AGGregatING (bagging) method has been widely used for improving simulation. The computational cost of this method scales with the size of the ensemble, but excessively reducing the ensemble size comes at the cost of reduced predictive performance. WebbAs we shall see, the nonparametric bootstrap procedure is very similar to a Monte Carlo simulation experiment. The main difference is how the random data is generated. In a …
