Diagnostics for Model-Based Seasonal Adjustment

Roxanne M. Feldpausch (1), Catherine C. H. Hood (2) and Kellie C. Wills (3)


Progress in seasonal adjustment depends on the development not only of methods that better account for the various components of time series, but also the development of better diagnostics. A successful seasonal adjustment can depend as much on the diagnostics as on the methods. In this paper, we try to identify promising diagnostics for model-based seasonal adjustment.
