WebSep 13, 2015 · We also have a computer simulation results over time to verify the performance of the model. The goal is to prove the simulation results and predicted values of the analytical model (which are both a time series) are statistically close or similar. By similarity I mean the model predicts the values close to what simulation is providing. WebA time series is essentially a sample of size 1 from a stochastic process. Resampling a sample is original sample, so one learns nothing by resampling. Therefore, resampling of a time series requires new ideas. Model-based resampling is easily adopted to time series.
