Model-Based Seasonal Adjustment Diagnostics
نویسنده
چکیده
Several model-based seasonal adjustment diagnostics are currently being incorporated into X-13-ARIMASEATS, a new hybrid seasonal adjustment program under development at the U.S. Census Bureau. These diagnostics have been implemented in the Ox programming language, and this paper discusses various aspects of the implementation. The diagnostics are normalized quadratic forms in the data, and roughly correspond to intraand inter-component variation. Disclaimer This report is released to inform interested parties of research and to encourage discussion.

Comparison of Time Series Characteristics for Seasonal Adjustments from SEATS and X-12-ARIMA
Two widely-used seasonal adjustment programs are the U.S. Census Bureau's X-12-ARIMA and the SEATS program for ARIMA-model-based signal extraction written by Agustin Maravall. In previous studies with SEATS and X-12-ARIMA, we found some series where the adjustment from SEATS had smaller revisions than the adjustment from X-12-ARIMA (Hood, Ashley, and Findley, 2000). Based on this previous work,...
متن کاملEstimating and Forecasting Network Traffic Performance Based on Statistical Patterns Observed in SNMP Data
With scientific data growing to unprecedented volumes and the needs to share such massive amounts of data by increasing numbers of geographically distributed collaborators, the best possible network performance is required for efficient data access. Estimating the network traffic performance for a given time window with a probabilistic tolerance enables better data routing and transfers that is...
متن کاملUnit Root Properties of Seasonal Adjustment and Related Filters
Linear filters used in seasonal adjustment (model-based or from the X-11 method) contain unit root factors in the form of differencing operators and seasonal summation operators. The extent to which the various filters (seasonal, seasonal adjustment, trend, and irregular) contain these unit root factors determines whether the filters reproduce or annihilate (i) fixed seasonal effects, and (ii) ...
متن کاملOptimal Seasonal Filtering
In this paper, I compare model-based and moving average-based approaches to seasonal adjustment. I propose an optimal moving average filter, designed to minimize the distance from a model-based filter. In simulations, I consider the accuracy of the alternative methods in estimating seasonal factors in a simple model. I find that the most reliable results are obtained either by the model-based a...
متن کاملThe Quality of Seasonal Adjustment: An Empirical Comparison of Various Seasonal Adjustment Methods
Abstract Using two basic assumptions of time series analysis, a test is proposed to assess the quality of seasonal adjustment of a series. The test is applied to several seasonally adjusted series of the Consumer Price Index (CPI) using three methods of seasonal adjustment: State Space Model Based Method (SSMB), TRAMO SEATS Method and X12ARIMA method. The empirical results are presented along w...
