WebA Hierarchical Dynamic Factor Model We assume that the data are stationary, mean zero, standardized to have unit variance after possible logarithmic transformation and detrending. Let Nb denote the number of variables in block b = 1 and let N = (N' + . . . + NB) be the total number of variables, each with Webproposes a factor model that uses common and block-speci c factors to capture the between and within-block variations in the data. Each block can be further divided into subblocks to arrive at a hierarchical (multi-level) model. A distinctive feature of the …
