 Abstract
In analysing a time series on the frequency domain, the spectral estimator (or periodogram) is a very useful statistic to identify the periods of a time series. However, the spectral estimator is very sensitive in nature to outliers, so that the spectral estimator in terms of M-estimation has been studied by some researchers. Pak (2001) proposed an empirical method to choose a tuning parameter for the Huber`s M-estimating function. In this article, we try to implement Pak`s estimation proposal in the spectral estimator. We use the Korean housing price index as an example data set for comparing various M-estimating results.
