摘要

This study proposes an approach for forecasting time series obtained from repeated samplesurveys. The approach applies a signal extraction technique as a preprocessing step to removenoises, due to sampling errors, from the surveyed time series data. Box-Jenkins ARIMA is usedto forecast using the preprocessed signal. The intended result is to show that this approachperforms better in terms of RMSE. An extensive computational simulation study is designed tosupport our hypotheses on various types of time series. Partial results show that for time seriesdata from repeated sample surveys, forecasting should be done using signals extracted fromsignal extraction approach in order to reduce forecasting errors.
