When the objective is to forecast a variable of interest but with many explanatory variables available, one could possibly improve by carefully integrating them. There are generally two directions proceed: combination forecasts (CF) or information (CI). CF combines generated from simple models each incorporating part whole set, while CI brings entire set into super model generate an ultimate forecast. Through linear regression analysis and simulation, we show relative merits each,...

in the prediction of quantiles daily Standard&Poor’s 500 (S&P 500) returns we consider how to use high-frequency 5-minute data. We examine methods that incorporate high frequency information either indirectly, through combining forecasts (using generated from sampled at different intraday interval), or directly, into one model. subsample averaging, bootstrap forecast averaging for indirect case, and factor models with principal component approach, both direct cases. show forecasting...

In forecasting a variable (forecast target) using many predictors, factor model with principal components (PC) is often used. When the predictors are yield curve (a set of yields), Nelson–Siegel (NS) used in place PC factors. These or NS factors combining information (CI) (yields). However, these CI not “supervised” for specific forecast target that they constructed by only but particular target. order to “supervise” target, we follow Chan et al. (1999) and Stock Watson (2004) compute...
