WebDec 7, 2024 · A factor-based bootstrap procedure is constructed, which conducts AR-sieve bootstrap on the extracted low-dimensional common factor time series and then recovers the bootstrap samples for original data from the factor model. Asymptotic properties for bootstrap mean statistics and extreme eigenvalues are established. WebFeb 4, 2024 · Under the assumption that the sample size n and the dimension of time series p tend to infinity together, the asymptotic properties of several robust estimators are established, including estimation errors and forecast errors. We also propose a detailed algorithm of constructing bootstrap prediction intervals for the high-dimensional time …
