After the preparation of data presented in Chapter 2, this chapter presents the different steps in the seasonal adjustment using the QGDP as an example. First, a national calendar is defined followed by the explanation how to use the calendar in JDemetra+. Using national calendars improves the estimate of the calendar effects. Some special days are already available in JDemetra+, but others need to be manually created. After that, single processing is explained, i.e. how to seasonally adjust a single time series. In the last section of the chapter, multi-processing is introduced, consisting of instructions for performing seasonal adjustment of several time series simultaneously.
