In this paper, the authors compare a trigonometrically designed low-pass filter with the Hodrick-Prescott filter and a conventional moving average. The authors examine by means of transfer functions, some practical applications and in comprehensive stochastic simulations how well the three...

This paper compares the efficiency of two methods explaining the cyclical movement of a time series at its current end. It refers to a newly developed low-pass filter and the seasonal adjustment method, represented by ASA-II. The empirical analysis starts with a visual comparison of the results...

The Baxter-King Filter shows some weaknesses, particularly with regard to monthly time series. This procedure involves not only a loss of data for the border areas of time series, but suppresses inadequately high frequency components and shows as a low-pass filter only the performance of...
