Seasonal Adjustment Using Structural Time Series Models: An Application and a Comparison With the Census X-11 Method
用结构时间序列模型（STM）对荷兰宏观经济季度和月度数据进行季节调整，并与普查X-11方法比较，发现STM方法表现良好。
This article makes the method of seasonal adjustment operational using suitable structural time series models (STM). This so-called STM method is applied to several relevant Dutch macro- economic quarterly and monthly time series. The results are compared with those of the Census X-11 method using several formal criteria as yardsticks. The STM method proves to compete well with the Census X-11 method in this respect.
