The objective is to help the user at each step of the forecasting process, starting with the construction of a database, all the way to the interpretation of the forecasts. The dynamic factor model adopted in this package is based on the articles from Giannone et al.(2008) andBanbura et al.(2011).

WebBy selecting different numbers of factors and lags, the dynamic-factor model encompasses the six models in the table below: Dynamic factors with vector autoregressive errors (DFAR) n f >0 p>0 q>0 Dynamic factors (DF) n f >0 p>0 q= 0 Static factors with vector autoregressive errors (SFAR) n f >0 p= 0 q>0 Static factors (SF) n f >0 p= 0 q= 0 Webmodels. Appendix A-1 summarizes the main equations of the four level model. 2.1 Related Work A vast number of papers in macroeconomics and nance have studied variants of the two level dynamic factor model. The di erence between our multilevel and a two level model is best understood when there is a single factor at each level. With K Gb = K F ...
