ABSTRACT
This paper analyses the time series observed for the foreign trade of the Czech Republic (CR) and predictions in such series with the aid of the SARIMA and transfer-function models. Our goal is to find models suitable for describing the time series of the exports and imports of goods and services from/to the CR and to subsequently use these models for predictions in quarterly estimates of the gross domestic product (GDP) component resources and utilization. As a result we get suitable models with a time lag, and predictions in the time series of the CR exports and imports several months ahead.
KEYWORDS
transfer-function models, SARIMA models, quarterly estimates of the Gross Domestic Product (GDP), imports and exports of goods and services, exchange rate.
